Delta-Trem Tube Tremolo

£399.00 – £509.00

The Delta-Trem™ authentically reproduces the alluring, hypnotic tone of “Bias” tremolos and the deeper more, intense throb of neon/photocell tremolos found in vintage Fender™ tube amps.

“…sounds bigger and deeper in a very tubey way compared to just about anything else you can step on.” — The ToneQuest Report

“Brimarize” your pedal! The Delta-Trem can be purchased with either new JJ tubes or grade ‘A’ NOS (New Old Stock) Brimar tubes fitted. JJ tubes are excellent tubes, however the NOS Brimar tubes were manufactured in an era when tube expertise and materials were at their zenith—they’re truly exceptional in terms of quality and reliability. Further, the longer plate construction yields a smoother, fuller tone than modern tubes.

Description

The Delta-Trem™ recreates the richness, warmth and “feel” of vintage tube amp tremolo in mono or true S-T-E-R-E-O! This is accomplished using vacuum tubes and an archaic, long-forgotten electronic device known as a “Raysistor“. A Raysistor is essentially a tiny filament lamp and photocell housed in a small metal can. This magical combination of vintage components enables the Delta-Trem to accurately replicate “bias” and neon/photocell tremolo effects, and a whole range of inspirational, unique tremolo effects.

The Delta-Trem’s fabulously versatile LFO (Low Frequency Oscillator) generates anything from a subtle shimmer to deep, thobby amplitude modulation (AM). In mono, use the Delta-Trem to faithfully reproduce the smooth, buttery pulse of an early Fender^® “Tweed” Tremolux amp. Or delve deeper, for the more intense throb of a Fender “Blackface” Deluxe Reverb amplifier for some good ole Louisiana swamp blues. In stereo, with two amps, the sound ping-pongs or swirls between them creating a huge, 3-Dimensional, spacious tone. This tremolo pedal always sounds exceptionally smooth and rich and blends beautifully with clean and overdriven guitar sounds.

FEATURES

Genuine Tube Circuitry: 100% vacuum tube and “Raysistor” audio circuitry creates the tremolo effect. The tubes operate at real amp plate voltages at 300V, just like in a vintage tube amp!
Smooth and Deep Tremolo: Advanced pulse shaping capability that replicates either smooth “Bias” tremolo or more intense, choppy neon/photocell tremolo effects.
True S-T-E-R-E-O: Link the two tremolos so the sound ping-pongs between left & right outputs. Or split them for truly independent operation, where the left & right outputs drift in and out of phase.
Advanced Functions: Rhythmic tremolo patterns with accented beats; Dithering of LFO waveform shapes for a more randomised tremolo; Phase control of the two tremolos from 0º-180º.
“Dakaware” Knobs: Bakelite Dakaware Chicago 1510 knobs custom manufactured for Effectrode in the U.S.A using the original 1940s moulds.
Turquoise LEDs: Pulsate with modulation speed for visual song tempo matching.
Includes 12VDC 1.5A Wall-Wart: High quality low-noise switched mode power supply operating from 100-240VAC mains input. Supplied with various adapter plugs to facilitate connection to mains outlets in other countries. Compatible with all Effectrode pedals.

Just tried out Tube Vibe, Phasomatic and Delta Trem individually then together in front of amp- Absolutely loving the Vibe and Phasomatic in front of Kraken (clean) Then I put the Delta in the fx loop and realised that’s where it lives- In front it sounds good- In the FX loop it’s something else- Such warm and complex deep modulated sounds quite unlike anything I’ve heard before from all three so great pedals

Hi Phil and Sam,
Well my Effectrode love just keeps growing! My Delta-trem is exactly what I was hoping for! I love the overall tone and the different rhythmic options available with the shape, depth and rhythm knobs maxed out! This is one groovy pedal that will never leave my board!
Keep up the great work guys 🙂
Cheers
Dan

I hope you and Phil are doing great. First off, I wanted to inform you that I absolutely love the fidelity of the latest Delta-Trem (Brimar) DT-2A. It has made itself a permanent spot on my pedal board alongside the two Blackbird SR-71 Preamps powering my stereo amp setup. The sound quality is beyond compare. I am still trying to figure out how to use all of the advanced options lurking within the DT-2A.

Hi Sam, I just want to quickly send my gratitude for the Delta-Trem and say unequivocally, it is the finest tremolo I have ever encountered. Thank you and Phil so very kindly for this work of art! This was my fifth purchase and I cannot wait for my next!

I got my Delta Trem in a couple of weeks ago and it’s killer. It’s the best thing in the world

Greetings from California.
It’s amazing how the most simple, yet complex, Effectrode ‘stomp box’ will let you touch the electrifying infinite tone one has been yearning for.
Phil, you have knocked it for six once again. THANK YOU for your Genius! Tone Meister!
The Effectrode Delta Trem has to be one of the most incredible, versatile, low noise, no tick whatsoever, hark back to the days of the origins and sound of electric guitar.
For years I have modded my trem circuit in my Fender Deluxe Reverbs, tried numerous pedals searching for the pulse and waited very patiently for the day when I could own the Delta Trem.
Yesterday it arrived.
WOW. I have spent 6 hours with the pedal now at the end of my pedal chain, into my handwired 64 Fender Deluxe Reverb, modded by amp guru Alessandro, into Celestion Blue.
Match made in Heaven.
You rock

Absolute perfection to my ears. Just the most rich, delicious swirl I have ever heard. I was waiting for “the one” and it actually rendered my speechless when I heard it throbbing out of my amp. The tone was huge but yet perfectly seated within my sound. It just sounded – right. It ain’t cheap but you get what you pay for. I play blues, roots and vintage soul music and this cannot be beat. Swampy throb, to a stage shakin’ stutter. In a sentence this pedal makes me want to play guitar more than I did before I owned it.

Kevin Kadish - U.S.A. 30th November -0001
So, I got my Delta-Trem yesterday… Dude, I love it!!!! Even as a tube boost it sounds great! The tone is stellar!!!!

Ricardo Wheelock - U.S.A. 1st January 2010
I recently bought two Effectrode pedals: a Tube Drive and a Delta-Trem. I tried both pedals today and I simply couldn’t be more happy!! I love their vibe!!!

Mark Filip - Great Britain 1st May 2010
Thanks for the prompt shipping. I received it and its a great unit, sounds lovely like my Vibra Chorus. Just ran my Moog into it and it works really nicely.

Vicente Muñoz - Spain 1st May 2010
Brilliant pedal. Best tremolo I have ever played, no doubt. It’s the most musical I’ve heard, can’t turn it off. No matter what setting it’s in, it’s beautiful. I’ve tried lots of pedals searching for the tremolo in my head and this is it. Genius.

Ed Oleszko - Great Britain 1st June 2010
This tremolo pedal far surpasses any other Tremolo effect I’ve ever used and really nails that vintage amp trem sound, it even makes my sometimes clinical sounding ‘modern’ amps sound like like the smooth buttery vintage models – excellent!!! I also must say that I’m loving the sound of the Delta-Trem with the depth all the way down which adds a lovely little warm boost – this boost sound alone is gorgeous mate then add on top the fantastic tremolo – stunning!!

Dave Ponte - U.S.A. 1st June 2010
I am a player of 20+ years , and have to say that the quality, reliability, and tone of your Tube-Vibe and Delta-Trem is nothing short of AMAZING!!!! I have been wishing for a Tube Delay pedal ever since you boys hit the market, as a matter of fact I actually requested it to you when you first opened up shop. You couldn’t ask for a better co-creator then Steve Rothery for the Tube Delay/Echo, so please, please put me on whatever list there will be to receive the first one’s made. I will be waiting very patiently until then. Thanks Again for the tone.

Todd - Vancouver 1st August 2010
This is an incredible tremolo; the absolute best I’ve ever heard in a vintage amp or otherwise. Worth every cent. But it is more than just a tremolo effect; it adds warmth and makes harmonics literally jump from my amps. When I’m not using the tremolo effect, I usually have the pedal engaged with the DEPTH knob fully anti-clockwise. This warms up even my most sterile amps and makes them chime like never before. No other boost/overdrive pedal I own even comes close to this. I have several high-end amps (Mesa(s), Dr. Z(s), Swart, Marshall) and the Delta-Trem really accentuates the harmonic content and warms up the front end on all of them.

Sam Lee 1st December 2010
The pedal sounds wonderful. I’m very pleased with it after much disappointment with other trem pedals. Thanks for putting out such a great product. I’m looking forward to exploring all the tonal options!

Tim 1st January 2011
I used the Tube Tremolo you built on my last recording with great results, ping-pong feature, which is absent in nearly every tremolo pedal I was considering came in very handy, thanks! Happy New Year.

Martyn Pratt - U.S.A. 30th November -0001
It was delivered yesterday and the baritone ‘lows’ came through beautifully. As I hoped, the Delta-Trem seems to be the best effect for this Tele baritone sound. Amazing job! My bandmates will surely be pleased.

Steven Byrne 30th November -0001
Got the tube in the post – thanks a million. I also managed to get my hands on a G.E. 5751 which has actually done the job perfectly, and I am using the 12at7 as a lovely subtle boost with the depth all the way down – sounds amazing. It’s a bit like having two pedals in one now, trem and boost, depending on which output I’m using. Using it with my old narrow panel Champ, sounds very 3-D and full, best pedal I have ever played!

Robert Kemp - Great Britain 1st March 2011
Well… I’m so pleased am I with the Delta-Trem that I’ve now bought
the Phaseomatic and Tube-Vibe from your E-bay shop.

Jime Hinkle 1st April 2012
I use the Delta-trem instead of my trem unit on my Super Reverb as it is far more dependable.

Greg Smith - U.S.A. 1st February 2013
I recently picked up a used DT-1A and am just blown away by how great it sounds, especially used in stereo. It’s so hypnotic. This is one of the best sounding effects I’ve ever heard and by far the best tremolo.

Greg Smith - U.S.A. 1st June 2013
I think I am on the waitlist for the new version of the Delta-Trem. I have the original version and absolutely love it. It’s one of my all-time favorite effects – a little tricky getting used to the controls, but the sound is phenomenal, especially in stereo.

Todd Tepper 1st December 2013
I have an older Delta-Trem that I love to death. It seems to give the signal the perfect boost or chime, even when the effect is turned all of the way down. Is this how you buffer the signal in the Delta? I feel strange about using it as a boost this way but it really gives the signal a chimey, bell like clean tone that I cannot get with my other boosts.

Jeremy Horst - U.S.A. 1st November 2014
I am an engineer in Chicago, Illinois. I have a Delta-Trem pedal (purchased on 2010 and containing the original tubes as supplied by Effectrode) that is used in a signal chain for recording guitar direct to tape via a Toft mixing console (no guitar amplifier). Having experimented with various processors and preamps in this signal path, I have found that using the Delta-Trem is crucial to achieving a convincing guitar tone in this direct recording setup. However, the best results have been produced using the Delta-Trem with the tremolo effect intensity turned all the way down, thereby using the pedal exclusively as a presence boost pedal.

Joe Caruso - U.S.A. 1st May 2015
All of us guitarists are very lucky that you put such so much love into your work! I always feel it a privilege to own and have your incredibly musical labors of love here on my boards. Now with that said, I was hoping that you might multi-task and finish the Lux and Delay too ???? Thank you for all you hard work! I hope I speak for all Effectrodians when I say – we appreciate your amazing vision, skill and hard work!
