ROG Brittania. I made it. Anyone else?

[Morocotopo]

Yup, just finishing the build. Made my own PCB for space reasons. A very nice low / med gain overdrive, very well behaved.

A few questions:

- The pair of LEDS in the opamp feedback , in my build only one of them lights up when playing at max gain. Is that normal or I have a broken LED? According to the schem, they both should behave the same way.
- The brilliance control is quite subtle. Is it supposed to be like that?

Congratulations to the Runoffgroove team for this great circuit.

EDIT: Actually both LEDs light up, but one of them is very dim. Asymetrical waveform?

EDIT 2: Just tried a Rangemaster in front. Wow! I´m gonna grow long curly hair. And lose a few pounds. Quite a few.  The LEDs in front are a great idea, you can use a booster in front and use it to increase distortion without changing volume.

I scoped the thing, at the output of the distorting op amp the waveform is symetrical, so no malfunctioning LED, just different lighting characteristics.

I´m gonna add a switch to parallell a cap to C2, at some settings the bass is a little thin. Cal it the "fat" switch. 2n2 or 3n3 work well.

Also, I might up the value of the brilliance cap, as it is it´s quite subtle, would be nice if it had a bit more drastic effect, specially to tame clean amps with bright caps on their gain/vol pots, that at low settings can be a bit shrill.

It responds really well to guitar volume pot changes, the thing. Very very nice!

I've almost got mine finished up - just got some trimpots and strip-sockets and want to wire it up this weekend.
At max gain, how crunchy does it get?

[Morocotopo]

Buck, it gets crunchy but it doesn´t go into full distortion. Sounds to me like a Bassman /old Marshall, sort of, regarding crunch levels. Think AC/DC. To get a Brian May lead sound, you need to boost it at the input, but as I said, it does take boosters very nicely.

One characteristic I didn´t mention before is that when the gain control is at minimum, it cuts the sound completely. Maybe adding an R to the pot´s ground leg would solve that. 10K or so...

Thanks - I'm looking more for REM/Tom Petty jangle-grit on up to U2/Edge crunch.
Don't need/want Brian May distortion/tone. I found the CB Galileo does that really well (albeit nasally) with the boost on.

I built a CM AC-Tone clone, which is a nice medium-gain distortion, but not so well on the low-gain.

What type of guitar/amp are you using it with?

[Morocotopo]

Buck, I tried it wit a frankenstein strat, chambered body, H-S-H mics. Through a tube amp at clean and lightly crunchy settings. Have yet to try it with my 335. It does light crunch very well, it has that treble "shine" that you can control with picking strength and angle, very responsive. I´m not that familiar with Petty /REM records but I think it´s brilliant for chord work, it doesn´t get muddy or messy with full chords.
