Kuston III Head [message #22696]

Hi, I bought a (late 70's?) Kustom Head. A Kustom III L (?) Could anyone tell me how many Ohms it is? I can't figure out how to insert a picture, so I'll briefly describe it...it has the script Kustom logo, no foam and tuck, 4 inputs, and has tremelo and reverb.

Any help would be appreciated

Your amp needs a 4 ohm load to get its full 130 watts of clean RMS power and should not be run at a lower impedance like 2 ohms unless played at low home type volumes!
It will be fine driving a 8 or 16 ohm load, but at 8 ohms it will only output some 70 watts of clean power and at 16 ohms half of that 70 watts.
Enjoy your baby!

by the way, does anyone know much about these heads. I've just hooked it up to a cab and my god the thing is loud. The tone for a guitar is ok, not great. Does anyone know if you can use it for a bass?

Yes you can use it for a Bass, However if you want to use it for guitar, put a multi processor pedal in front of the amp and you will like the sound...Kustom has a LOUD clean sound and they take pedals very very well.

Yes ,pedals and such work well in front of them but be sure to let the amp provide the volume otherwise if you drive too hot of a signal level into the preamp you stand a chance of popping the input IC chip and or having bad distortion when you hit a hard chord or note!

That's funny that you mention getting distortion when hitting a hard note or chord, as that's exactly what's been happening! I've just put new speakers into my cab, so I'm now trying to work out what's happening. Thanks for all your comments

For sure sounds like you are over driving the front end of the pre amp. Turn the gain down on the effects and you should be good to go.

With a solid state preamp your overall / end result volume level should not be much more than when you plug straight in thru no pedals!

here's the problem. I am getting a distorted sound when hitting a hard chord when plugged directly into the head! I'm wondering if the input ic chip has already previously been damaged?

Try this...

My Lead III has a volume control for each channel and a master volume over on the right side of the control panel.

Lower the volume knob to the 9 o'clock position for the channel you're plugged into and adjust the overall volume with the master.

Master volumes should always be set to at least 50% of wide open!

Why 50%, stevem?

To relate it to let's say a V6 motor in your car why would you want to have 3 of the 6 spark plugs unplugged if you had to drive up a big hill ?
Or ask yourself why solid state stereo home or even surround sound units have no master volume?

To me the only use for a master volume on a SS guitar or bass amp is to cut back on the amps wattage if it happens to be driving speakers that can not handle its wattage!

But... different combinations may produce different sound, so there are no right or wrongs, right?

Exactly, every amp is different and some sound great when the preamp is really cranked and some don't sound so great.

I think that the amp has two input jacks per channel. One is a lower gain and one is a higher gain. Try both and see if the distortion is better or worse when using one or the other jack.

Also try working with the tone controls, they can make a big difference in the overall tone. They may not work the same way that your other amps tone controls work, so experiment and see what you can do to make the sound better to your ears.

Yes, there is no right or wrong unless the preamp is opened up so much that it is clipping.

Yeah, Chicago Bill is right, mt head only has two input jacks per channel. The Problem is the consistency, sometimes it works fine and I get a nice tone, and then it will just start to 'fart out'. Very frustrating. Channel Two seems to work fine, but I don't like the sound without a bit of reverb and tremelo. I'm not sure if it's worth getting it fixed or not. I might have to throw it back into the ebay pond!

It worth opening up the amp and un-plugging all the white Molex connectors two or three times as I am just thinking that it could be a bad connection making for you issue also

Right, I gave that ago and I've just played it for 30 mins and no problems. The difference, so far, is that the volume goes up gradually rather than go from zero to blow your head off. I hit the strings really hard and no troubles, but I didn't put the volume past three as I'm at home! The proof is going to be in the pudding of playing with a full band, if the amp keeps going as it is I'm going to try the amp at a gig I'm playing next Friday (with a back up amp near by!)

I find I can get a really nice tone with my strat, but I'm struggling to find a tone I like with my 12 string, will keep trying.

Thank you very much for all the advice Smile

This amp is a kind of Fender, and I think channel 2 are not worth playing. Awesome with pedals on channel one. Forget channel 2, sound is so bad.

What do you mean by bad, all mids to the tone?

Sorry, I mixed it up with a Kustom Studio 2 valve I got, channel 2 was sounding bad. As I recall(dont playing it for years) the Kustom lll Lead only have one issiue, the distortion is bad (clipping)But I love it for the tremolo and the clean
