Double Bass Recognise This?

#66
There seems to be a piezo pickup in the bridge too. Look at that cable below the bridge that vanishes into the body.

For the support. It is simply too thin. Wind something around it to make it thicker and use things that stick and don't rotate around the support.
For my Clevinger support I used two rubber foam tubes that are supposed to be used for bikes. The inner layer was spirally cut, closely wound around the support and fixed to the support at the ends. The second tube goes over the first one.

Yes the hip support is crazy thin, good idea on using rubber to cushion it. I've spent the evening playing with out the support and my fret arm/wrist aches. (Definitely need to get a better position/technique)
There is a piezo in the bridge, not sure just yet how the first 2 knobs work ,1 Is bridge and 2 is the p bass style but both have to be on the get sound. They dont seem to work independently ?

I got it now thanks for the info. Its late in the uk so my amp was down low. It seens the piezo is quieter but with the amp up to normal volume (sorry neighbours) its there and sounds great with all the blend to the bridge.

If there is no battery for a preamp the piezo might be quiet because of a low impedance by the internal electronics. I tried that once with my bass guitar connecting the piezo in parallel with one of the magnetic pickups. The piezo is almost impossible to hear. That is a design fault that is rather common because the designers are not really into electronics and use schematics that work with magnetic pickups unchanged with piezo pickups that does not work.

If you do not want to put in an impedance buffer for the piezo which also needs a battery, the best you can do is install a switch that puts the piezo directly at the hot contact of the output and at he same time disconnect the electronics from that hot contact. That's the best you can get with a high impedance input of the next external electronic part (preamp or amp).

Oh wow that's it !! Thank you for putting a name to the otherwise nameless eub.
The eub is in near mint condition, tiny scuff on head stock and a little mark near the neck pickup. Electrics are all good (once I changed the battery) and it plays and sounds great. The seller has had it sitting around for some time and only played it now and again. I guess I got really lucky
