michael-faces Posted August 19, 2010 Share Posted August 19, 2010 (edited) I started a thread asking about running a bass into a guitar preamp, and I got loads of helpful answers, but its led me onto another question. Is it possible to run two preamps in a single chain? I don't have two preamps at the moment (second one should be arriving soon), but I'm just curious as to how it would sound, and if its even possible. Would this be a dangerous thing to attempt, and would it result into a catastrophically awful sound? In this case, I'd be running a guitar preamp, into a bass preamp, then into a power amp and a cab. Please let your thoughts known on this! Edited August 19, 2010 by michael-faces Quote Link to comment Share on other sites More sharing options...
Colledge Posted August 19, 2010 Share Posted August 19, 2010 running 2 preamps in a row is fine, infact an active bass is essentially a bass with a built in preamp, so whenever someone runs an active bass into a bass amp, they're using 2 preamps. The only thing you will have to take into consideration is that the gain on the second preamp will be lower than if you where running a passive bass straight into it because the signal coming from the first preamp will be stronger.

Please let your thoughts known on this![/quote] personally i'd just run a single preamp no real advantage to running two in a row, there are some disadvantages though such as noise rejection / levels will rise and overall distortion will rise aswell. What're you trying to achieve? you may be better off looking at pedals if your after distortion. Quote Link to comment Share on other sites More sharing options...
michael-faces Posted August 19, 2010 Author Share Posted August 19, 2010 Thanks colledge, you helped a lot on my last question too! Another quick question, would there be any danger for the second preamp if I was running the first preamp really loud? Quote Link to comment Share on other sites More sharing options...

michael-faces Posted August 19, 2010 Author Share Posted August 19, 2010 Thanks umph. I am after distortion. I'll check out about noise rejection levels now (I'm new to this by the way!) Quote Link to comment Share on other sites More sharing options...

michael-faces Posted August 19, 2010 Author Share Posted August 19, 2010 Ok. What I was thinking of doing was running the guitar preamp into the bass preamp, so when I wanted a clean sound just turn the guitar preamp off. Then when its on keep the volume low so its adds a guitar like distortion to the clean bassiness of the bass preamp. I'm not sure if that makes sense at all though. Would a half decent noise reduction pedal remove most of that noise? I could also use a noise gate for when I'm not playing. Quote Link to comment Share on other sites More sharing options...
Colledge Posted August 19, 2010 Share Posted August 19, 2010 theres some really nice distortion pedals arround or even multi-fx pedals that can emulate a guitar amp / cab.... i think those would be easier, cheaper and better options to be honest.

michael-faces Posted August 19, 2010 Author Share Posted August 19, 2010 I've tried a few of them, and yeah some are ok. Really looking for a more unique sound though. Also I'm getting this as a spare preamp for my guitar, so I thought I may as well put it to good use on my bass, if I can. Quote Link to comment Share on other sites More sharing options...

In terms of sound, what you suggest doing would alter your tone - whether you 'll like it or get what you want ---- you'd have to measure that to your goals.

Mr. Foxen Posted August 19, 2010 Share Posted August 19, 2010 Pretty much going about it all the wrong way. I'm using a guitar preamp and a bass preamp at the moment, run each into separate halves of the power amp, and run different cabs from them. If you put a guitar preamp into a bass one, you don't get guitar and bass sound, you just get guitar sound, since the lows are already gone so the bass pre can't amplify them.
