I didn't knew they were sold ready to go. I've used this kind of approach in some guitars. Anyway, I hardly ever use them or tone pots for guitars, but I like them the other way around (as hi-pass filters) for some amp circuits to keep the lo-end tight and focused while turning the volume up. Sometimes the Bass knob on amps is not a good one to solve flabbiness. Orange, Matchless or Bad Cat used these circuits in their amps.

RC and LC filtering circuits were widely used for guitars in the '50 and '60s tough they dropped popularity by late '60s. Fender used these filters in the early Esquires, or Jaguars and Jazzmasters. Gibson had the Varitone. It was also widely used by German makers. The Schaller or Star pickguards have this kind of filters on-board, or from the DDR, Simeto stuff has them too. This Musima Record has two filters (I cannot see more that two capacitors there). One is an RC high pass filter paralleled to the bridge pickup (Switch position 3) thinning a the sound a bit. The other one makes also an RC filter but this time connected in series with the neck pickup acting as low pass filter, leaving a really muddy, dull and useless sound. A severe treble bleeder (switch position 4). LC (inductor-resistor) were also used, but inductors are much more expensive than capacitors, so only a few builders used LC resonant filters for some "exquisite" products. Examples for this are the tone circuit of the Ampeg V series amps from the 70s or the Gibson Varitone sometimes found in the ES-335 guitar family.

I have to say that if I ever want to filter something I prefer to make it this way, fixed or selectable fixed RC filters. I've never favoured conventional tone pots. Most of the times I rewire the pots as fixed resistors to turn them into fixed bleeders, or just completely disconnect them from the circuit.

I see You're knowledge of these things is way deeper as mine will ever be. I am glad when I'm able to solder a pickup cable to a volume pot and a plug ;) .

I visited my Musima Record over Christmas at my sister's place, but I couldn't take pix of the inside because I didn't have the right kind of mirror with me. It does have the same top carve as shown in Snap's pix.

As far as wiring goes, it has an entirely reversible mod, as done by a previous owner. He completely replaced the pickups and wiring. The black plastic spacers on either side of the pickups sit on the footprint of the original pickups. I made some adjustments when I got it, but it works great as is, so I think I'll leave it the way it is for now.

Wow! What a beautiful curly back. I like it even more than the tiger striped figure in mine.

Humbuckers? I don't like 'buckers on thinlines that much. I like them on solid planks for heavy rock stuff, but nothing else. It's like comparing a ES-335 and a ES-330. 335s are good but 330s with P90s always have a nicer janglier voice I love. Drop a couple of Simetos back on your Record, I bet you won't ever miss those 'buckers.

Yes, that is the general plan, to be executed whenever I get around to acquiring more Simeto pickups. I don't have any loose ones. I need to buy a few more crappy East German guitars with decent original hardware, to refresh my box of parts, (unless you have a pile of hardware to send me, of course).

Not much parts at this moment. I'm also hunting crap DDRs with good parts for organ transplants.

PS, Wait, I think I mistracked this circuit. It's difficult following it in the reversed images of a small mirror. Forget all I said above for now. I'll try to track it right this time and post about it.

Ok. Something is wrong. i'll have to recheck the whole circuit because weird things happen. Currently the switch acts this way:

1- Bridge PU -both volumes
2- Both PU -rear volume
3- Bridge PU -high pass - rear volume
4- Neck PU -Lo-pass (bleeder) -rear volume

It's really strange that the first volume knob only works in position 1 and does nothing in the restant positions, while the second knob works in all positions. Kinda weird.


It's really weird... but correct. According to the catalogs, the typical (standard in most models) Musima circuit with two pickups and three knobs is arranged this way:

-"Trickschalter für Rhythmus, solo, banjo und shearing effekt. Volumenregler für alle effekte und 1 volumenregler für Rhythmus-effekt."

-Selector for rhythm, solo, banjo and shearing effect. Volume control for all positions and one independent volume control for rhythm position.

So it should be:

1- Rhythm: Bridge PU -both volumes
2- Solo: Both PU -rear volume
3- Banjo: Bridge PU -high pass - rear volume (funny way of calling this. it's a rather useable sound for certain situations).
4- Shearing: Neck PU -Lo-pass (bleeder) -rear volume (My wife calls it "efecto nubarrón". That means "big dark grey cloud effect" in Spanish. A really good description of this useless effect).

It's really strange that the rhythm setup is the bridge pickup alone, while most old guitars in the universe have the bridge pickup labeled as solo or lead instead (the bridge pickup has much more upper mids content so it cuts better through a mix). Here the solo position engages both pickups instead of the usual bridge PU. No other brand I know did things this way. This is what surprised me. Why two volume pots in the lead position? Simple, for the Musima guys this is the rhythm, so a second volume here makes some sense, if you turn it a bit down, when switching to the solo position a volume boost happens. Simply the old school way... but reversed!

What keeps me still amazed is: what was the nubarrón effect intended for? And why the neck pickup doesn't work alone and unfiltered in any single position. :? Certainly the guys at Musima had their own way of doing things. At least in a way hard to understand for occidental minded guitar nuts? :mrgreen:

What I want to do is disconnecting the cap shunting the mids and treble to ground from the neck pickup in position 4 and leave the rest alone. I can live with this arrangement excepting the drastic bleeder.

. The Berlin-label Roger Super model was transformed slightly into the Musima Record - an acoustic archtop at the top of the product line.
I took these two but I can not say they were very luckily , these Transformers!
