    Is the BTB-01 as powerful as the J-Retro? I fail to see what the difference is, but then again I know very little about preamps.

    If you can get Bass, Mid, Treble controls and still retain the bass' original tone control, what's the diff? Where's the tradeoff on tone or versatiliy?

    Thanks,
    Matt:confused:

    The BTB is strictly a 2-band (bass and treble) EQ, plus a "bright" switch. The J-Retro includes a sweepable mid control, and also an active blend control (separate buffer preamps for each pickup before they are blended together), an active/passive switch, and a pickup selector switch.

    The BTB has a single stacked control, so it should be possible to combine it with your existing controls. The J-Retro is 3 stacked controls and a couple of switches that comes pre-mounted on a Jazz-style control plate (the U-Retro is the version without a control plate), so you wouldn't combine it with other controls.

    I just saw this preamp the other day on http://www.bestbassgear.com/btb-01-preamp.htm, and have to say that I am curious. I was looking for a two band preamp to put in my Marcus Miller Jazz, and this seems like it could be a contestant alongside a Bartolini circuit and a Seymour-Duncan circuit. Or maybe an Aguilar - I just can't choose!

    Any more info on these?

    What kind of info are you looking for? It's a two-band EQ with stacked controls--essentially the B/T section of the J-Retro preamp.

    Also, are you aware that East makes a J-Retro preamp specifically for the Marcus Miller Jazz?

    Well, just opinions or feedback from people who have the unit. I guess it's been out for a while now, but I've never heard anything about it.

    I was aware of the Marcus Miller preamp, but a) it's a _lot_ of money and b) I would rather just have to the two band than a three band with sweepable mids.

    Gotcha!

    You might browse the J-Retro forum over on the Dudepit (http://www.vintagebass.com/thedudepit/forumdisplay.php?f=7). Also, JP (JPBasses) uses the BTB-01 on his custom basses, so you might try looking for his postings on the subject.

    One simple issue I can see with using the BTB in your MM is that it has a single stacked pot instead of two separate pots for bass and treble. Rewiring it to new pots is probably possible, but likely to be a bit of a pain. However, I understand that East can do custom orders...

    The stacked bass/treble controls are exactly what I'm looking for! I'm planning on putting in a two-band preamp with stacked controls and then making the fourth knob a passive tone control.

    Ah, that makes sense!
