KB300 please help!

[MarcelVD]

Hey guys, I have a question I hope you guys can help me decide how to use my KB300 Peavey combo. I have multiple options. I own a 1978 Fender p-bass and I am wondering how to plug it into the kb-300.

I was using that kb-300 since I was the keyboardist in our band for awhile since we couldn't find one, but we did find a basplayer instead. Well now that the basplayer left and we did find a keyboardist, I'm switching back to bass.

So instead of buying another amp I want to try the kb-300. Roast it if you want but I think it should be able to sound pretty vintage and it's LOUD!

Now my options are:

1: Plug it in the kb-300 preamp. ( one of the 3 channels) The normal way so to say!
2: I have a Sansamp fly rig V1. I can plug that in the pwr amp in and bypass the preamp of the kb-300.
3: Plug the bass straight into the pwr amp in without any preamp whatsoever since my 78 p-bass has an awesome vintage sound of it's own.

I have a Boss CE-3 chorus and a tonepress barber compressor also so for option 4: I was thinking using option 1 and connect them between preamp out and pwr amp in ( effect loop).
I could use also option 2 and use the chorus and compressor from the fly rig instead.

See my dilemma? I hope you guys can help me decide whats best.

Much appreciated! Thanks a lot in advance!

Don’t do option 3.

 

[Nebadon2000]

My guess is KB300 has line level inputs if so maybe Option 2 if Sansamp has line level output

Along the lines of what Nebadon2000 said, those pedals are probably meant for instrument level, probably not best for an effects loop or between pre/amp.

Try option one and two and figure out which you like best.
Skip option three unless your P-bass has been modded with an active preamp.

The high impedance inputs are only 33k ohms, so actually not such a normal option for passive basses.

If it were me I'd probably just run a pedal into one of the instrument inputs and call it good. It's only a 150 watt amp though, and weighs 81 lbs...

This is the best option, and imo the only practical option.

Oke that might be another option to try. Thanks.

I think I'm just gonna plug the bass in one of the channels. I tried the Sandamp but it makes the sound more modern. I'm striving for the natural vintage sound of my p bass.

If you haven't already, try the Sansamp in bypass mode, in the hope that it will impart less (or best of all, none) of its "character" to the signal.

You aren't going to get that with 33k input impedance.

You have the wrong tool for the job.

It will sound anemic and dull going into the Peavey inputs. FYI.

So what advantage will it add if I use the Sansamp in bypass mode except from being able to use the tuner?

The bass will have a 1Meg ohm load instead of 33k ohm. It will sound like the bass should sound, not dull or weak. The Sansamp will also present a more appropriate signal level to the line-inputs on the Peavey.

The Peavey is a line mixer with a power amp and speaker. It's not designed to interface to a passive instrument, but to keyboards with very different impedance and level characteristics from that '78 P. You'll get better results using a preamp (Sansamp) to "translate" the impedance and signal levels from the passive P to the KB300.

Now, if your concept of "vintage bass tone" is dead flatwound strings and the tone control rolled all the way back, then you might not hear much difference, but you'll have to turn up the level a lot to get enough signal.

Only if it's always buffered and not a true bypass device.

All the other Sansamps I've ever used were buffered and not true bypass. I assume the Fly Rig is, as well.

I don't know if it is or isn't.

The Bass Fly Rig V1 is buffered (copied from the V1 manual):

I'm using roundwounds. I certainly don't like the dead sounding flats neither too much clarity and treble making it sound modern. I guess I like a warm tone with just enough clarity to bring out the natural vintage low mids and mids between 150 and 800 hz. So you definitely got a point here. I will try to put the sansamp into a channel and bypass it and hopefully that will boost things up a bit without colouring the sound into a more modern sounding one. Thanks.

Than that should work.

I can't possibly remember the details of all the gear out there.
