I've decided to give the church amp another go

[telechaser]

It's a Peavey Studio Pro 112.

When we we're still doing our service in a basketball court (indoor of course), I didn't really like it at the time. Now that we're meeting in a smaller venue it might sound better. I just picked it up from a member that was keeping it and giving it a try. So far it sounds ok.

We'll see this Sunday I suppose.

I don't know whether this will help you. I have a Bandit, similar to but more powerful than the Studio Pro. I have a couple of suggestions:
1. Get the amp off the floor. Use a stand that angles it back a little, or use a chair and put a book (later Harry Potter series are about the right thickness) under the front of the amp.
2. Don't place the amp square with respect to the walls.
3. Use the clean channel and get your distortion (if you use it) from pedals.
4. Have a look at the owner's manual for tone settings suggestions, as a place to start. (www.peavey.com/support/searchmanuals; there are several versions of the Studio Pro, so you'll have to find that). I've found "jazz" and "clean blues" to be good starting points.

Good luck.
