Amp For Multiple Instruments? Options

[musico2007]

hi i'm fairly new here but i got a question...i'm trying to get an amp that will work good for both my guitar and synthesizer, i have a nord lead 2x and a semi-hollow body guitar. I think my synthesizer mest up my current amp which is a 30 watt Crate amp...i've heard that playing sum low notes on a keyboard/synth can mess up sum amps because of the low frequencies...is that true?

I know that there are several keyboardists who have been known to run their keyboards thru guitar amps to create a distinctive sound. Jon Lord (Deep Purple) did it regularly and I have heard that Depeche Mode have been known to do it during recording.....what I don't know is if they used something akin to a "reamp" style box to convert the signal or not. You definitely need to do it if you run a signal from your computer interface's output (or analog tape deck) to a guitar amplifier....you can screw up your equipment very badly if you don't. That is about all I know on the subject.

" I know that there are several keyboardists who have been known to run their keyboards thru guitar amps "

Let me try to answer that from a guitarist point of view:
An electric guitar pickup delivers a low-impedance electrictal signal you will have to amplify a lot to stick out.

A keyboard sound, on the other hand, most always uses some preamplification like in a Rhodes (Transistor),
or a Hammond (Tubes).
Run an analogue synth like an ARP, or it's digital emulation through a tube powered guitar amp, or them emulation,
well, you will end up for the moment at Miami Vice theme by Jan Hammer or the whole story in his "Escape From Television"

P.S: Make sure you always use a limiter before the digital siglnal goes the the amp, it might start burning
