What do the controls do?????

:shock:
I recently bought a used Dobrolectric at a local shop

It is basically a thin line tele with a biscuit cone and a p90 pickup at the neck position and some kind of Piezzo type pickup on the bridge.

there are 3 knobs on the guitar body.

The top one, closest to upper bout, is the volume control

the middle one is some kind of tone control, but with a push-pull feature on the switch. It changes the tone, but I'm not sure how it does this

The third knob seems to blend the pickups, but if you try to put all Piezzo, you wash out and get nothing.

So.....

Dobro/Gibson experts, what exactly does the push/pull function of middle knob do

And

Why don't I get all accoustic pickup when I roll the third knob away from
the p90 postion and all the way back to the Piezzo position?????

Thanking everyone in advance

You got me skibumdog. I'm surprised it isn't obvious when you twiddle them.

all I can sugest is to go to the companies site if they have one or see if you can google a guitar repair forum to see if they can help.

I think what you may have there is a peizo blend setup.

I believe you may have to run the peizo signal through another amp....like a stereo jack setup. The blend knob allows you to go p-90 by itself, peizo alone for a more acoustic tone, or a blend of the two(very cool effect, btw). I've seen this on some Parker solid bodies I've played.

I'd contact a good Gibby dealer to be sure, but I bet that's it.

Otherwise....how do you like that thing?

I really like it.
The P90 has an amazing tone range by itself
Blending the pickups is fun too.
I'm still not sure about the push pull tone control. It seems that in the up position is works mostly for the Piezzo (sorry, I don't know how to spell it, as well as I'm generally ignorant about this type of pick up in general)

Every guitar has a story, which is a lot of the fun. I bought this one at the Olde Town Pickin' Parlor in Arvada, CO. This is mostly and acoustic shop but they sell Nationals and other resos and somebody was selling this on consignment so they could buy a Martin.

It has Dobro decals on the headstock and a Dobro logo on the case, so I don't know if this is from before Gibson acquired them or when.

Seems to have more "personality" than the National Resolectric, though this is a nice instrument too. The fact that I could afford this and not the Resolectric pretty much was the determining factor over which guitar to buy that day.
