hi Skip

on newer amps I guess it's fairly common to see speaker out ohm ratings of 4, 8 and 16. but on the older pa amp heads I am seeing some of those values like 4 and 8 but often higher ones like 30,60,125 even 500. 

are these still in use today or are these obsolete or maybe related to the original use of these heads which were PA purposes and not rocking out?

Danger, long question to follow...

Playing seriously for three years. Wanting to fatten tone watched Dave's 59 bassman series...awesome. Saving up the 800 bucks for a '90 reissue, found a 59 Bassman pedal from Boss for 80 bucks. 

Know what?  That pedal is pretty good. On my '76 Princeton it's replicating that 59 Bassman pretty closely. I'm happy.

Hi Skip

I am at the moment studying the harmonica and slide guitar in the style of blues rock. Please could you provide some information on the type of amp I would need for the harmonica and slide guitar (hopefully one amp for both instruments), the mic for the harmonica and any effects pedals that I would need along with any prices that you may have

I live in England.

Many thanks for your help.

Skip:

A few years back I bought an Ampeg GVT5-110 as my first amp. I could never figure out the treble and bass settings. Each has a circle at the 12 o'clock position and can be rotated CW to the 5 o'clock and CCW to the 7 o'clock. There are no numbers. The manual doesn't explain them well. I've fiddled with them, but can't seem to discern an optimal setting. Would you happen to know more detail on the treble and bass adjustment? continue reading...

I came across this product while looking for an amp for use with harmonica. Has anyone used this amp and, if so, would you recommend it?
