400 Stereo Amp? [message #8898]

I bought a 400 stereo amp an have a few questions.

I can't tell what the stereo function actually does or is supposed to do, i dont have enough cabs to really test it. It appears that this is set up like 2 amps in one, is it as simple as it sounds, it splits each side of the amp to the same side speaker outputs?

Also, I love the harmonic clipper feature but the volume drops quite a bit with it on, even with the volume boost it is considerably quiter, is this the way it is or is there a known fix maybe?

Thanks for your input.

PS Does anyone know which model this is, no back plate.

Harmonic Clippler + Volume boost + Bright on right

Reverb, tremolo, + bright on left

thanks again.

I don't have one with a Harmonic Clipper. BUT ! @

http://reviews.harmony-central.com/reviews/Guitar+Amp/produc t/Kustom/K200B/10/1
One reviewer states: "The other goodie is called a Harmonic Clipper, but what it really is, is a built-in fuzz. That's right, not overdrive, but an actual '60s-vintage fuzztone like a Maestro or a Tone Bender!" and "Flip on that Harmonic Clipper and you're off to another universe full of jagged shapes. The most brutal, crude, wicked buzzsaw distortion this side of an overpriced vintage pedal resides within."

Who nose ? ... might be Fogerty's K200A-4 !!! could be Rolling Eyes

nevertheless, I'm jealous, I want one Surprised

The k400s output section is made up of 2 k200s, you can run it in stereo if you want with only 1 cabinet hooked up and you will not hurt the unuesed power section, but I would run it( to be on the sfe side) in mono if you will have it on for more than a hour at a time.
Your speakers may not beable to handle 200 watts RMS, but if you do not play the amp above 4 or so on the volume control it should not a problem for your speakers.

The harmonic clipper is definately fuzz, i experimented a ton last night.

I made my cab 4X12 stereo 4ohms on each side and plugged into each side of the amp, only using one output per side(because I don't have any other 4 ohms cabs).

I split my guitar signal so I could use both sides of the amp(s).

Using both sides makes the volume drop on harmonic clipper channel almost irrelivant and I now have more tone possibilities than I know what to do with. Using both channels takes a little edge off the clipper, and yes there are many fuzz tones there.

So, splitting my guitar signal and running a stereo 4x12 sounds wonderful in mono, and better in stereo unless I turn the volume up on the left side, this creates a high pitched squeal that is feed back realted at lower volumes but does'nt go away at higher volumes when I turn the guitar down............. any ideas what would/could cause this? Could it be some sort of feed back because its a stereo cab and everything is so close together?

Otherwise this amp seems to be in fine working condition, even with the two relatively small problems (volume drop on harmonic clipper side and squeal in stereo mode) this amp was a great purchase.

I think maybe the volume drop is normal and you are supposed to use both sides?

I am yet to play a K250, but I can't imagine it offers much more tonal variety than this amp.

I want to order the schematic for this amp, so if anyone can tell which model it is I would appreciate it.
