Just found an ibanez cp9 I was going to replace with my optostomp which do u guys think would be the best? Keep the opto, or get th3 ibanez cp9 oooor a maxon ?
Remember that Maxon made all of Ibanez's pedals up until the 1990's; so an older Maxon CP9 is exactly the same thing as an Ibanez CP9. The newer Maxon CP9Pro+ is an entirely different circuit though, so it's not like an old Ibanez CP9 will give you the same kind of results as the CP9Pro+.
The older CP9's lose some low end and are a bit noisy. They can be modded for better low end, if you want to do some soldering.
In that case, swap the input cap for one of 10x the current value, and look for C12--it should be a 1 nF from the factory, and you'll want to swap in a 470 pF. If there's no C12 marked, or if it's not a 1 nF, then I'll have to go back though my old notes to remember what exact part of the circuit that was.
does that mod prevent it from being a squash machine? i had one i bought for like $25 and sold it for $50. i was quite happy with that exchange. nothing i hate more than squashy compressors. sometimes they sound cool on guitar but i hate them on bass.
