Hollow bass circuitry

[fretlessman71]

I've noticed that both the standard Hofner basses and a lot of the Gibson 335-ish basses (I know it's an EB-something) have a switch or a button that totally changes the character of the tone. On the Hofner, it's the switch that is marked "Rhythm/Solo"; on the Gibson (Epiphone Rivoli, too?), there's a push button near the bridge. Are these both doing the same thing? And just what ARE they doing without being active? Are they adding something or taking it away?

I believe its a phase switch for the pickups.

My Rivoli had a little transformer attached to that button that, I can only assume, acts more to load the pickup a little. I know that reads badly, but loading the pickup can result in some cool tones!

It's a baritone switch on the Gibsons, knocks out some bass I believe.

So maybe it's an impedance kind of thing? You think the Hofners are doing the same thing?

I own an Epiphone Jack Casady and it has a switch wired to a transformer that switches the impedance of the pickup. (50, 250 and 500 ohms).

If you do a search on Electar, JCB-1, varitone, Casady, etc. you'll find lots of info.

These switches are found most commonly on short-scale basses... On some it's a "choke" switch, on some it's a "baritone" switch. I think originally they were for players to be able to play melodic stuff that isn't "bassy," to avoid cluttering the low end should there already be a "bassy" part in the song. Of course one could just use this function as another bass tone option and turn up the low end on the amp or in the mix.
