Im new to playing bass, I picked up an amp. Can anyone tell me about all the features on my Peavey 115 Combo Bass Amp. It has a 9 band eq, pre and post gain dials with bright and punch buttons, compressor with level and comp/limit dials, Patch input and output, crossover with high and low ouput, preamp out, power amp input, it says bw equipped on front of cabinet. On the back to the right of the heat sink is a remote switch input, and external speaker (minimum 4 ohms). 210w rms@4 ohms, 300 w rms @2 ohms, 28v rms. Any info on this amp would be appreciated (like how to use the features, aside from the eq). Thanks, Rock on.
