You can run it from the FX loop or Preamp out, but not from one of the speaker jacks. If you are not using the 5150 for sound, you have to pull the power tubes from it too, to prevent the thing from melting down.

I already downloaded the manuals of both amp.
What the best choice to drive a Roland E-20 Synthesizer and a mic ?

Hi. I'm new, to this forum, to the KB 300, and to the electric guitar itself. I recently started trying to teach myself, and so far, so good. I acquired a KB 300, with the Black Widow, at a local pawn shop for $60. They were under the impression that because it said "keyboard amplifier", that it wouldn't work with an electric guitar, so they priced it low "just to get rid of it". As I said, I'm new to all of this, but I know a bargain when I see it, so I promptly paid the pawn shop man ( borrowed a hand truck from him. 88lbs? Really?) And loaded the amp on my truck before anyone in the pawn shop had time to rethink their pricing guidelines. I admit, I even glanced in my rear view mirror as I drove away, because I felt like I stole it.
So now, I'm just looking for some advice on the amp. What would be "best practices" when using it, and very importantly, how do I correctly run effects pedals through it? Any help is greatly appreciated.
PS: I'm playing a Fender Squier Strat and an Epiphone "Special" GS through it. I have a Joyo Ultimate Drive Pedal, Danelectro Fab...Fuzz, Flange, Echo, and Metal Pedals. I also have a Digitech RP55, but as I have not yet received my degree in Rocket Science, I don't use that one much. :-)

It is an amplifier. It has several identical input channels to accommodate a keyboard use, but you can amplify anything you want. It won't have features common to guitar amps, like overdrive. But if it makes sound you like, that is all that matters. Use it like any amp.

USUALLY we run the gain pedals between guitar and amp. That is overdrives, fuzztones, distortions. Time related things we often prefer to run in th FX loop. That would be delay/reverb, chorus and flange, compression.

But you can run an echo pedal out front if it pleases you.

Hi! I have a Peavey KB/A 300 that I bought used with the Rhodes electric piano that I play through it. It's always worked for me until recently it just cut out while I was playing and hasn't made noise since. If I recall correctly it kind of gave a last gasp unusual noise before it died but I might be making that up. i'm hoping it's as simple as replacing a fuse or something but I'm not finding anything like that without opening anything up. I know the speaker was replaced by the previous owner before i bought it so maybe that was blown out again. Does anyone have any suggestions for what to look at to identify and hopefully fix the problem?

Thanks,

Dan

It could be a fuse, but they are inside, so...

I'm not opposed to opening it up. I'll see what I can figure out. Any guidance would be much appreciated though as I haven't serviced this amp before.

Thanks,

Dan

Hi Again I just found this nugget of information on a different site:

"The amp does not come with built in fuse protection. It stopped working one day and I HOPED that I could simply replace a fuse. As it turned out, the input power stage was completely blown and some major components needed replacing. Special parts needed to be imported from Peavey USA and the repair procedure took several weeks. This is in my opinion extremely poor design and I am surprised to see it from a big USA name brand."

(from: http://www.harmonycentral.com/reviews/p ... 300/473295)

It doesn't sound like it's as simple as I'd hoped. Does anyone else have experience with this issue?
