Matched NOS Mullard OC140/950 Germanium Transistors NPN.

Ask about stock or special needs as I usually have these in stock. Or if you want something special like low gain or super high gain, cap choices whatever. I do a lot of one offs for people!

Keeping with the car theme the Glass Pack pedal was derived from a Tonebender 1.5. To me that is the sound in my head I was looking for and continued through the 18 month journey to version 21. You can read about the TB 1.5 and it’s influence to the Fuzz Face and other Fuzz pedals and considering only a few were ever made it seemed the unlikely candidate, but it did create a world of sound.

This pedal started way before the Nitrous pedal did. The first 10 versions were various two transistor versions of the 1.5 using PNP to start then NPN to settle on. It was then suggested that I add a tone knob to the circuit which meant another transistor. I ended up with 8 versions of tone circuits and thought I was complete and yes this version is available with three germanium NOS NPN transistors. I then considered making a discrete low dropout regulator that would serve as both a bias and lower the noise. The first one was with a 2N404 germanium transistor. That version is available in small quantities. The next two used silicon transistors which made the circuit a little more stable.

This version has 2 switches. Switch SW1 will defeat the tone circuit if you want the classic Tonebender 1.5 sound. The second switch SW2 will change the high pass filter on the front end. If you want a heavier sound then engage this switch and like the original it will go down to 7hz. The default is 250Hz using the best Mial caps on the input (also used on the output). All the transistors in this design are direct coupled including the shunt regulator and phase is true from input to output.
All the audio pots are custom made for us to military standards by Precision Components in Canada.
Like everything I make the parts are off the charts compared to others. The caps are Mial Silver Mica and Black Gate BGN and BGN HiQ (look them up most cost more than this pedal on eBay). Power supply caps from OSCON and Wima film. Soft turn Kilo knobs on all of these.
Other versions available on request including a limited number of 2N404 shunt regulated versions and some standard versions. This one is considered TurboCharged.
Any questions don't hesitate to ask. Solo from Rob Fetters Heaven is done with this pedal. Each pedal is hand built by me one at a time.

Thanks, Gordon
