Coming in summer – The ‘Glass-A’ Triode Buffer

Coming this summer. The ‘Glass-A Triode Buffer’ is designed to do just one thing, but it does it exceptionally well. This compact audiophile buffer is based on a N.O.S. subminiature Philips ECG triode tube operating as a cathode follower at several hundred volts. The result is a superior buffer device with staggering dynamic range and a very wide, flat frequency response. This little buffer has some outrageous specs.

Frequency response is essentially flat from below 10Hz up to over 100KHz (-3dB break frequnecies lie well above and below these points).
It can handle signals over 50V peak-to-peak with no clipping distortion.
Two parallel cathode follower stages ensure whisper quiet operation and excellent drive capability.

The Glass-A adds more clarity, depth and detail to the sound of any musical instrument to greatly enhance it’s tone and the way it reacts. More details coming soon!

Looking forward to hearing it with my pedal steel/volume pedal combination! I'm a long time buffer fan and would love to be using a tube device if I can hear the difference?

Hi Tommy, You'll almost certainly hear an improvement in clarity and definition when using the 'Glass-A' tube buffer because of its drive capability. How much of an improvement will depend on your setup, cable length, guitar pickups, amp input impedance and effects.

Hi Phil, I wish you all the best for 2015. This buffer looks really interesting. How will the Glass-A be powered? Same adapter as other Effectrode pedals, 9V, ...? How will it interact with the Mercury Fuzz which is supposed to not like buffers? Finally, would you mind advising me in which order you would put these pedals: Effectrode Mercury Effectrode Fire Bottle Effectrode PC-2A Buffered Wah pedal Thank you in advance, Matthias

Hi Matthias, Happy new year to you too. In my opinion the Mercury will be better without a buffer before it - even the 'Glass-A'. The Glass-A would be better placed after it becuase it's output stage is a much better cable driver. Regarding pedal order, I use this order of FX (mostly): Mercury->PC-2A->Fire Bottle.I'm not sure about the wah though, you'll have to experiment a little an see which works best. It may work well before the Mercury, it may not.
