    I recived the bass last thursday and it is pretty playable out of the box, i was very suprised considering it just went coast to coast. Great playing bass and i will start a new thread with pics in a few days but i need some help with the pick ups first. I am trying to figure out can you solo each pick up?, isint the control when in the middle an even blend example second knob J and Humbuker in the middle would be the blend. When the say magnetic pick up their talking the J and Humbucker right. I notice with the master volume all the way up and the J and Humbucker in the middle and the third knob turned all the way to the right full piezo it seems this combonations lacks out put. Any direction on how to use these blends and adjustments in the control cavity would greatly be appreciated. PS I think this is a well constructed bass and i really love the greenburst finish.:)

    I would call Carvin customer service 1-800 #

    You did just buy it new from them. It think some customer service would be in order here. They will be able to explain the controls and expected output from any combination of tweaks to the controls.

    They have always been very helpful on the phone.

    I found out the other day that you can order a wide 5 piece walnut/maple neck (neck-through) for a 5 string with an undrilled/unshaped headstock for a project you may never get around to.

    They should have sent you a nice detailed sheet explaining the knobs (?)

    Anyway, the top row of knobs is master volume, J99 vs. HB pan control, and J99/HB vs. piezo control. The bottom row (smaller knobs) is bass, mid, treble control. Try everything center and work from there.

    I basically center the J99 vs. HB control, and have the J99/HB vs. piezo control paned over to the magnetics with just a little of the piezos blended in.

    Have fun with your new bass!

    I'm sure that you can. One of the blends is between the front and rear magnetic pickups, and the other blend is between the piezo and the magnetic pickups. If you turn the second blend all the way to piezo, you are soloing the piezo pickup. If you turn it all the way to the magnetic pickups alone, you can then use the other blend to solo either the front or rear pickup by turning the first blend all the way one direction or the other...not too complicated, really.

    It may be that the gains on the piezo pickup are not set high enough. I can see from the catalog that there are individual trimpots in the control cavity for the gain on each piezo saddle. If there's not a "master gain" for the piezos, you might try turning one of those trimpots to see which way boosts the gaiun and which way cuts it.

    No problem. Once you've spent a bit of time playing around with it, definately give us your impressions. I haven't played many piezo-equipped basses, so I'm curious how you end up liking the piezos.

    Still working on the out put still seems a littel week with the combo of maset volume all the way up J and Humbucker evenly blended full piezo, i think i will go into the control cavity and see what i can do. I will let you know how it goes
