Would either the Kasino Club PA head (100 watts -w- reverb right?) or the Kustom II bass head (2 channel with bright; no reverb) be a good amp for guitar?? THX!!

The bass head would have a input impeadence set to work with pickups, you stand to much of a chance of clipping the preamp in the PA head with the hotter level out of a pickup compaired to a mic.

Can you change impedance on a 67" 745 PA head to handle the hotter signal of pickups?
What is clipping the preamp? Overdriving it? What damage can that do? Mine sounds
awesome with tone to die for but there is a little overdriven edge to it. Is that edge caused by clipping of the preamp?

Steve,
I am curious how you came up with this. In my k200b model 2 and the 5 (pa), they use the same preamps (105), and power amp/regulator board (703). Not trying to be a smart aleck, just trying to learn more.
As far as the KII, I just fixed one for a friend, and tried it on bass and guitar, and it had great high AND low end, seemed to work great on guitar and bass. I use a pa amp and the standard amp for both, and haven't noticed any difference. Steve may have some additional insight from the tech point of view, he's a good guy and always willing to help!

Thrill Bill:
I don't want to speak for Steven, but what he said is true of modern design equipment.
You are correct that the Kustom 200 A and B series used the same pre-amp circuits, and the same boards in both PA and guitar amps. I don't know anything about the Kasino designs, but I'd guess that there is little difference between the guitar and PA pre-amp circuits in that line either. The Kustom engineering guys knew how to get the most out of their designs.

Hey jimi earl,
Try playing with your guitar volume control on only 4 or 5.
At 4 or 5 on the guitar, you are probably not overdriving the preamp, so you should be able to get a clean sound out of your amp. If it is still clipping it could be a problem somewhere else, maybe the output section.
Also, the 745PA is referred to in the 1966 Ross catalog (on this website) as a “modified K200”. The catalog says “Total of 4 microphone inputs.” So they must have added some kind of mixing circuit on each channel so each channel could run 2 mics at a time. (see “Frankin cascade” posting of 4/4/04 for more info.) So apparently the preamp in the 745PA is different from the guitar preamp –so it is possible as Steve said that it was made for mic signals and could be distorted by the stronger output of guitar pickups.

Thanks for the responce. Can damage be inflicted from the hotter guitar signal going into the 745PA's inputs designed for mics? Earlier posts say theres no difference
in preamps regarding PA and guitar amps. It sounds to me like they used the same design,
at least in the early days, Jimi
