If you don't know what an fx loop is you shouldn't be trying to mod pedals.
Church.
Just go buy an mxr micro amp for 59 bucks and call it a day.
Call it a mistake if it doesn't do what he thinks it will do. And he likely doesn't know if he's asking.
Oh the irony.
Here's my story, and you can listen closely, or completely ignore me. I have in my possession many,
many compressors. Guitar pedals and rack mount units. They're all subtlely different, but remarkably similar. I was crazy buying them all, but some were so cheap used I thought if I don't like them I'll flip them over. I ended up keeping them all, so I can still go back and reference them.
Boss doesn't make a good compressor. I use my old MIJ CS-1 occasionally, and it's the best of the Boss lot. The CS-3 is just noisy and overloads easy. If you have active pickups or put a booster in front (like a line driver), it's just bad. The only plus is that is has a tone control. With the popular mods for it, it becomes a decent, but mediocre, compressor. It
is cheap, so if money is an issue, whaddaya' gonna do? I say.......
The Dyna Comp is actually nice. Dirt cheap, and it works. The hidden secret is the trim pot inside which is the 'attack' control. It's preset, but who says you can't mess with it? No mods needed. $69 and it compares to boutique pedals quite nicely. Yes, it's made cheaper with cheaper parts, but it still works, and it's still $69.
The BBE Opto-Stomp is the best 'cheap' guitar compressor pedal. $100 and it is optical, so it isn't just like the 99 other VCA compressors I have.
If money isn't that big of a deal, the Maxon CP9 Pro+ is 'it'. Carl Martin's two units are also amazing. He makes a 'budget' compressor, and his 'pro' compressor (optical!). They both are excellent.
There ya' have it! If you want/need a compressor pedal, here's my 2¢.
Stay away from
the Behringer BLE100, Dan Armstrong Orange Squezzer, Dan Electro Surf & Turf, and the new EH
Soul Preacher. You'll thank me later.
Try as many compressors as you can. Get a feel for them, and you'll pick a winner quickly. No mods neccessary. Remember waaaaaaaaaaaaaay back you wanted a gainy sound? Maybe you don't even
need a compressor. But if you have a Dyna Comp with a Keeley Blues Driver you've spent a couple of hundred bucks to improve your tone. If you just want to goose your tone for lead work, go to
http://harryj.net/OD_Shootout2.htm and pick the pedal
you think sounds closest to the tone you hear in your head. If you shop used you might even luck out. That's my 2¢ and I swear to Christ I'll shut my trap on this subject now. Thank you for lending me your ear.
