This is my first post. I have a Kustom 200 B1 amp. With my bass volume switch all the way up, then start to turn the amp volume switch up. The volume starts off low then with a 1/16 of a turn the volume is very loud. I have to turn down the guitar switch way down. Any idea's what is wrong. The bass cabinet is 2-15s 4homs speakers wired in series gaining me 8ohms. Thanks

There's two channels in that K200 amp, does the volume control on each channel act the same way?

Your taking about volume controls by the way , not switch's.

I'm talking about the 2 volume controls on the amp. From low volume to very loud with just a touch of the volume knob. Both channels act the same. Thanks

So in that case both volume pot's are bad, and or there is a bad solder connection from the pot to the board it's mounted on.

The 2 volume knobs act the same. With the bass guitar turned up to 10. As I start to turn the volume knob up. It starts off low then very loud with just a touch of the volume knob. I have to turn down the guitar volume. Thanks

Yes, I understand what your saying and my reply to you stays the same.

The impeadence of your speaker cabinet does not come into play here, so it's irrelevant.

Thanks for the info. I'm bringing the amp into the music shop later today to have them look at it. I will give them your thoughts on the problem

Is your bass active? (Does it have active electronics?)

Hi. No my bass is passive. Gibson SG. 1916 year. I spoke to the tech at the shop. He said its sounds like just dirty volume knob. So i sprayed them with electronic cleaner. It is working better. The volume increases slower. My plan is to spray it every few days. Thanks

Spraying it out every few days is not needed once the resistive trace grit has been flushed out of it.
What's needed to be sprayed in them now if they are working normal is a potentiometer lube spray, as this will stop the ware that made the grit and the cutting out in the first place.

I have a wah pedal that used to require far-too-often cleanings, which I'd always done using straight alcohol. A friend (local brick-and-mortar music store owner, repairman) recommended CAIG DeoxIT for the very reason you mentioned- dealing with the tiny scratches and pits left by grit that had been on the pots' contact strips when the knobs were turned. I've heard/read that there are different formulas of DeoxIT that shouldn't be used in different situations (a formula with a flammable ingredient on/in something carrying a considerable charge, for example...maybe the only example LOL). Is there a reason it shouldn't be used in this situation?

I second the request for advice on which of the DeOxit products to use for cleaning pots. The Caig website has a confusing and intimidating array of products - for instance, The "D-Series" is a "UNIQUE CONTACT/CONNECTOR TREATMENT, REJUVENATOR AND PROTECTOR", whereas the "G-Series" is a "CONTACT ENHANCER,CONDITIONER & PROTECTOR". So they both Protect, but one "rejuvenates" whereas the other "enhances" and "conditions". Hmmmm. oh, and there's the "S-Series", which is a "LUBRICANT & PROTECTANT FOR BETTER METAL ELECTRONIC CONNECTIONS & CONTACTS.". Hmmm, that sounds good, too, but apparently it doesn't "Clean" or "Condition", only lubes and protects. What to do, what to do?

Ahh, here we go - the "F-Series": "Removes Contaminants, Lubricates & Protects Moving/Sliding Contacts and Carbon-based Controls" That sounds like the ticket! $28 bucks for a 5oz can. Seems a bit pricey.

Anyone have any experienced opinions on the Caig products?

I will post a long reply on this whole subject tomorrow.

Yes, Caig products are the best.
