Hi folks, I was wondering if anyone has tried bridging channels one and two on thier SC150? It's a fairly common thing to do this with the vox AC30 but, knowing very little about this SS amp I fear I may damage the amp. Thanks, John

Hi, you can jump the channels on ANY amp as long as one channel does not have reverb, or a added gain stage as in many new tube amps. If it does than the two signals will be out of phase and you will get a big loss of tone/frequence responce, just like you had a guitar fitted with a in and out of phase switch. This effect will be dependent on how loud one channel is in relation to the other.

if I understand you correctly..you are talking about what we always did with the old fender amps...plug your guitar into input 1/channel 1, then run a cord from input 2/channel 1 over to input 1/channel 2. Just a reminder, that the kustoms have a resister (cap?) on the input labeled "high" so its not the same in/out like it was on the fenders..you can remove that of course...best yet, just go back to that Morely ABY pedal I keep braggin on, then you can split to channels or better yet to a pair of amps! and you'll look twice as kool....

Great advise, I'm always looking for tone variation with my amps but, I didnt want to destroy this Kool Kustom amp before I even got to use it at a gig. Although this SC150 is loud in my house, I'm thinking it may not have enough power to get overtop the drummer out at a gig. Two of them is not a bad idea, I'm still looking for a K200a-4. Any opinions on the builtin distortion of the K200? Thanx, John

Use a morley ABY, safer and more options are available to you. If you need more power, but like the sound that you get from your 150, buy another one and use the ABY switch to combine them or split them up. I have used one side as effected, and the other side as clean--makes for a fat two player sound if you then combine them. Jsut a thought...... 8)

I do this a lot....with an ABY switch or the old Fender way ET mentioned. I have a couple of bass heads that I have cut the Capacitor on to make the high inputs the same as the low so I can strap the channels together with the same signal if I forget my pedal. I have had no problems doing this and it gives more tone control...really fattens things up. We did a live recording recently and the recorded sound was just thin on my bass....but when I added the second channel I was able to get a good playback sound. The two channels also work great with Rickenbackers with stereo outputs.....one pickup to each channel!BC

YES gang,but understand what I wrote. (If you are bridging and amp with an effect channel you will get phase problems) not a bass or what ever head with just two plain channels.In a fender the two inputs on each channel are for different gain, on 100s and 200 kustoms the inputs are marked high and low in refercence to tone.If you hook up a amp and get phase problems it will not hurt the amp, just you ears.

I use a different method. I have two Kustom 200's. I use a stereo delay pedal made by electroharmonics and run the dry signal to one amp and the wet to another. Its now 400 watts and I can even set one amp up to grind and the other smooth or have delay in one while the other is straight. It sounds like two bass players at once.

Which one you wanna hire. One plays thru a 3x15 silver 200. The other plays thru two 2x15's cascade cabs with a charcoal 200 head. They both like to run a little under where a four would be on a kustom volume dial. Some times the tall boy turns down a little while the short cab guy turns up to about five for a grinding distortion that only a cranked kustom can deliver while the other one turns down to about two to keep the oveall volume down to a sane level. Both bass players seem to favor and old 60's hofner bass due to its low tones. I hate to be either one of these guys roadie with all those cabs though.
