Timmy derivatives?

The schematic @MichaelW posted says TL082 looks like

The schematic says TL082 but the board says TL072. I doubt you could hear any difference. Having said that, I think the OCD sounds better with an 082.

Seems I recall maybe @Chuck D. Bones saying that TL082 were TL072 that weren't up to snuff, but I could be wrong!

I thought that 082's were hi-er fi versions of the 072? Dunno....but I have some heh.

Nope other way around, TL082s are noisier than TL072s, AFAIK they’re cut from the same sheet then binned for performance.

I could have it reversed been a while, and I could be wrong on the IC's as well.

The Luxury 763 (Lovepedal BF Deluxe) is YAT with TS-style clipping (one of the Timmy's toggle options).

The Grey/Gold Ghost Super Six is virtually identical to the "Super Stevie" (Super Six SRV Mod), but that's not surprising considering all of these pedals are derivatives of the OD11, which is a derivative of the Timmy.

Interestingly, if one were interested in building the Lovepedal Brownface Deluxe, you could achieve that on a Luxury 763 PCB with the following changes:

D1 and D2: yellow diffused LEDs
R7: 3.3k
Gain: A250k
Treble: B10k
Volume: A10k

And yes, it's extremely low gain!

Back again with more information that nobody asked for!

I got to peek inside a Lovepedal Amp808 last night and found the following changes to the OD11 side (referencing the Luxury 763 PCB for part values):

D1 and D2: 1N4001
R3: 3.3k
R7: 3.3k
Gain: A250k
Treble: B50k
Volume: B100k
Opamp: scratched out but appeared to be 4559

Opinion: The Treble knob (particularly the linear taper) makes the pedal seem really dark. I recommend using a smaller value pot and/or adjusting the taper to a reverse audio like the newer Timmy version.

So there you have it!
