ordered this for myself, but ended up building it for a friend’s birthday gift.

i had high hopes for this circuit, it’s definitely gotten a lot of praise around many parts of the internet.

it’s really hard to make fair assessments of pedals like this when i’m a lot more used to better tools for the job (real tube amps, amp sims+IRs), so i compared it to a couple other similar high gain preamps/distortions (REVV G3, SLO pedal) to get a ‘baseline’.

opinions:
- 18V mode is mandatory. 9V almost sounds unusable to me. wtf.
makes a huge difference imo.
- i don’t really like the big muff style tone control on circuits like this. a proper tonestack would be nice. regardless, it works and sounds ok.
- ‘gate’ controls like this are stupid and i don’t like them. chokes the hell out of the tone and makes it sound like shit.
metal nerds use proper standalone gates anyway, stuff like this is really unnecessary.
- the ‘tight’ control is more subtle than i thought it would be, adjusts a bit than just lows, cuts into low-mid territory too, and that’s ok.
- the ‘style’ toggle switches between the two different pedal circuits ‘Tight Metal’ and ‘Tight Rock’ - the circuits are just that similar they can be switched on a dpdt.
the switch essentially functions as a mid scoop toggle. lmao.
i actually like the rock mode better. metal mode is a bit too scooped for me.
- yep ‘mids’ is a mids scoop toggle.
- ‘boost’ is sick. it’s like another channel. the high gain channel i guess. sounds better than the alternative imo.

it’s got a heck of lot of volume on tap (in 18V mode at least, 9V mode may as well not exist, and it's an insult to the mighty LT1054)

i reckon it sounds best into FX loop vs in front of amp.

here’s a very rushed demo, had to get this one banged out quickly late at night before tomorrow when im giving it to my friend. i still haven’t had a chance to try boosting it with an OD808 yet, but i might get to tomorrow.. (like most distortions, i reckon it’ll sound better with the sweet caressing love that comes from a mid-boosting overdrive)


overall, i guess it's pretty good for what it is. it had a better bite than the REVV G3 (vero clone), SLO pedal is good but it only has like x1 good sound. at least this has a variety, but is all that variety useable? depends on the user i suppose.
somehow i still think the pussy melter is better than all of them. i never expected to be saying this but here we are. still yet to do a brown betty build.

I built this thing back in Jan, I didn’t really play with it a lot,(a little more than just functional testing) seemed decent enough for a pedal. I’m with you one the tone stack, I would trade all the setting and options for a tried and true TMB. So there it sits on the shelf. One of these days I might actually give it a proper audition. I wanted to really love this pedal but it failed to hold my interest.

i’ll be honest, after all the praise i saw on SSO for this supposedly being one of the best options for a solid state high gain preamp… im underwhelmed.

Sounds pretty good to me. I'm working on one right now. Any values you would change from stock?
no idea, i haven’t really studied the schematic that closely.
mods would depend on what you want from it that the stock circuit won’t give you.
i guess you could possibly look at the tone control circuit block and see if improvements can be made there?

What’s SSO?
 
I've finally gotten the chance to play around with this one a bit. The cut and boost switches in the up position with the gain cranked is where it shines for me. I'm going straight into a JC120

JC120 😳 damn that’s about as stiff and clean as it can get. must be doing alright if you can get a good high gain rhythm sound on that with this amptweaker thing.

It's an early-ish one from about 83 that is extremely broken in. And just because I think it sounds good doesn't mean it actually does, but it definitely makes me want to keep playing. I'm just playing around the house so what do I know 😁

I think the hi cut switch on the TM is really what makes the difference between it sounding decent or like a typical box of bees type distortion.
