Re: JOYO Crunch Distortion Schematic [schematic]

finally found the time to change the caps. C8 changed to 39nano and C9 to 47nano, less middy now. I think I could get the mids that I want with 56nano but I ran out of caps. may be will change it again next time i have the time. again the desoldering on this board is frustrating, i got myself 2 new ...

Re: JOYO Crunch Distortion Schematic [schematic]

Yeah, its that funky lead free [or whatever it is] solder that they use. I did several mods to mine already,one was to was add a three way on /none/on switch with 3 assymetrical 1n4148's /no diodes/ 2 1n4148's. I prefer the silicones to the leds in this thing,and actually no diodes sounds close eno...

A few BOSS pedal problem DS1 & HM2

A friend who runs a rehearsal studio just dropped off a couple of DS1 and a HM2. The newer DS1 is healthy but the 2 old pedals which needs ACA adaptors are acting up. I'm pretty sure these 2 were used with a variety of AC adaptors which i suspect is causing the problem. Also they are quite old and n...

Ibanez TSA5 - 5W Tube Screamer Amp

Got this at a good price during sale. I read its based on the Champ? using it at home for practice, nice basic sound from 1 Vol and 1 Tone. The TS circuit is a bonus but i rarely used it since i i'm running pedals. it stopped working a few days ago and at the dealer right now to get it fixed. i didn...

Re: JOYO Crunch Distortion Schematic [schematic]

Simmed the tonestack with LT Spice and the Tone and Presence interact a lot. The Tone control has the greatest effect with the Presence altering the roll off slop. For the least mid-range, try the Presence trim pot about midway. Might increase the cap in the presence control, to 47n for more action...

Joyo - JF-39 Deluxe Crunch

Picked this up last week, have not played much with it unfortunately. More than enough gain but i find that i'm wanting more from the Pre and Tone. This sounds more open than Joyo's Crunch (crunch more compressed to my ears). I stack overdrive pedals in front of it to make it tighter. Cracked it ope...

Re: JOYO Crunch Distortion Schematic [schematic]

Thanks for the trace and schematic, was going to do it myself but didn't realise it was a 3 layer board, you just saved me a lot of heartache. Just got it used but found that it had too much MID for my taste. the crunch box was one of my first build and i remember it not being middy. the schem will ...

Re: hand painting w/ brush and acrylic paint
