Verified. Works great. I wasn’t a fan at first but it’s growing on me. My only “problem” with the pedal is that it doesn’t really stack with anything else, I’m assuming due to the Rangemaster section? Is there a way to make the Rangemaster switchable? I was going to build a Supergroup preamp and a separate booster that way I can get the Sabbath tones as well as stack it with other dirt. Since this one is already built could it be done with the existing layout?
I’m thinking just putting the input on an SPDT switch and having lug one go to the normal input on the board and the third lug going straight to the drain of Q2, would that work?
Wait, a DPDT for the boost. Lug one to board input. Lug two to guitar input. Lug three and six jumpered together. Lug 4 to A-1 and lug 5 to M-1. Remove the jumper from A-2 and M-2.
Ok. Got it going... SPDT switch... lug one to G1 (normal board input), input from switch to lug two and lug three to M1. I was surprised how much effect the boost has. It goes from stoner/door to classic rock/blues. I thought the Super Group was much higher gain but compared to some YouTube videos it’s a close approximation. Maybe someone else will find this useful too.
Awesome, thats sounds rad, thanks for the tip. I think I will build it soon and try the witch. Hmmmm, I wonder how it will behave with other boosters in place of the Rangemaster section?
I was thinking that too. I didn’t get to play it much yet but it seems to stack really well with the boost off. I ran a Sonic Titan, Pharaoh and Black Forest (clones) through it and it sounded great. I’m thinking of adding a boost pot (won’t look pretty) and changing the 22nf input cap to a cap blend pot like the Red Rooster. Maybe reducing the amount of boost may give it a bit more versatility too.
Changing the 10n to ground (In series with the 22n for treble 1) to a lower value also brings out some more shred from the circuit. I put a 1.8n a 3.3n and a 6.8n on a SPDT on/off/on toggle for 3 values, one being close to stock. The lower values make the treble knob less pronounced but also not so thin and buzzy. Great circuit

ReplyDeleteI forgot to thank you for the layout (and the Quantum Mystic) so thanks for sharing your work with everyone.

ReplyDeleteLug 2 to bypass switch, not guitar input.

ReplyDeleteSo I built another one with no mods. I did notice on the thread at FSB that the 100uf at the emitter of Q1 should be 47uf.
ReplyDeleteThanks for the catch! layout updated.
