RARE DOD 410 Studio Bi-Fet Preamp Vintage Guitar Bass Effect Pedal. Not reissue!

Hello !
Up for sale is a rare gem of a pedal from DOD....the Studio Bifet Preamp 410.
There is no footswitch on this unit....meaning it's always on !  Perfect for adding nice bifet sound and warmth to whatever signal you apply it to !
The volume has a terrific range and so does the tone control.  So you can adjust your sound on the fly as necessary!
You can go with it into the front of your amp and use it as a 2nd preamp to improve the sound of your amp's preamp. Or you can bypass your amp's preamp altogether and go into the power amp in (also effects return) to go straight into your amp's power amp.  The only thing about this is that you lose your amps overdrive and parametric eq controls, etc. unless you plug the bifet preamp into your effects loop (i.e. BOTH the preamp out/effects send and power amp in/effects return) and plug your guitar into the front of the amp!
The pedal also has a low-z (XLR) out so you can plug into the XLR input of you power amp or console or what have you.
There appear to be two holes drilled in the back of the unit (see last pic)....not sure if this is why the tone gets bassier when you turn the knob to the right and gets more treble-y when you turn the knob to the left. Regardless, it doesn't affect the sound quality of this unit as it sounds terrific !
If you know what this unit does and are familiar with it, then you know you don't have to ask...just get it !
Please read the condition description, these listing details and examine the pictures carefully.
In good to very good shape considering its age. If you are buying this pedal to look at and admire its condition, then you are missing the point of this amazing piece of equipment !

Thanks so much for your interest and I hope you buy it now!!!!!
