NBD - Rob Allen mb-2 Custom

Received my grail bass a month ago from a seller in Italy. Koa top, f-hole, 33" scale, fretted mb-2. The neck is more D shaped than other RA's I've owned, and despite having developed a love for slim necks, I find it very comfortable. There is a mag pickup in addition to the piezo. Volume and pickup balance (with detent) controls in the bridge. Came with a matching koa ramp which appears to never have been installed (the double sided tape still has the wax paper strip on it) that I'm going to install soon. Reverse headstock provides a slightly longer travel for the low string (and it has the string-thru plate on the back to extend the ball even more enabling regular scale strings).

The bass arrived strung B-G (despite the ad stating it was set up for E-C, and which a previous owner mentioned long ago) and buzzed like crazy. New strings and close inspection revealed that the nut was poorly cut/modified (and loose) and the bridge saddle slots were very worn down. I took it to my luthier immediately and he installed a new bone nut and new saddle, as well as extending the bridge angle slightly and cutting compensating string slots to achieve a near-perfect intonation. He also repaired the binding where it was coming separated at the shoulders (and where someone else had tried to repair it previously and left some excess glue).

It weighs about 7lbs.

IF I'd had the opportunity to spec a custom order for this bass, I may have asked for a slimmer neck. But everything else? It's totally my dream RA.

It sounds amazing - the mag pup and piezo are not extremely distinct from each other but (a) there are adjustments I can make in the control cavity I haven't explored yet, and (b) they blend really well so far. Bonus: the way the bass engages my pedals is surprisingly pleasant. The reaction of my Mooer Sweeper (recently plugged in and dangling at the moment!) and Tender Octave pedals and Fliptop Boost to the signal made it seem as if they were waiting for this bass. My other passive and active basses sound good through them, but not this good. Fun.

Picture!

Thanks! I've owned a few that totally fit my purposes for just a season/band opportunity, but they were eventually sold. Here's a pic of the one that started it all; my first mb-2 5 string:

I picked that one up from Corner Music in Nashville around 2008? I guess.

The phone photo in the OP doesn't do this new one justice. The contrast of the koa grain is incredible.

Hey Jeff, that's a beauty!

Any chance you can post more pics here so we can see it better?

Thanks, and congratulations!
:laugh:

I'll get some tomorrow!

yeah, more pics is always cool --- but the second (live playing) pic really shows it off!

That's actually an old photo of my FIRST mb-2!

i know that's a quality piece, but the fact that you enjoy playing it is the bottom-line --- congratulations on your new instrument! :thumbsup:

Truth. And thanks!

It is, actually--another spec I wouldn't have asked for, but I'm enjoying (and I suddenly realize that it explains the neck shape). It's actually 14mm!

Wow- the Gerald Veasley Ibanez signature is the only other one I know of with a 14mm spacing. On the plus side there's a lot of extra space on the fretboard to widen it is you want to have the bridge recut.

I've got a 1988 Modulus Graphite Quantum-6 SPX with 14mm (actually, slightly less: 13.97mm to be precise) string spacing. It uses an off-the-shelf Kahler 2450 bridge with the saddles slammed up tight against one another.

Over the years I've definitely discovered some techniques that are easier to execute with 14mm than on a bass with wider spacing...but also a few where it's more difficult on the narrow instrument. Don't think it would ever occur to me -- either 30-something years ago when I ordered my bass, or now after having lived with it for so long -- to explicitly ask for 14mm string spacing on a bass.
 
14mm?! So it seems to me this is a 4 string body and neck (lefty - look at the headstock) that were converted, originally I suppose, to a 5 string bass. I wonder if it came out from Rob with the magnetic pickup. Enjoy it!

I'm pretty sure it was a custom from the get-go and the mag pup is original (the ramp also matches the pup cover). And the headstock was a deliberate reverse to extend the potential winding length of the low E string (per Rob). It's just a crazy, creative custom!

Pics!

Wow, what a beauty! I'm curious about that bridge, it does no look much like the one on my Mouse. Wonder why it's so different?

I love the integrated thumbrest on yours! And the swoop on the end of the fingerboard. I've seen that before on his instruments and I think it's cool.

Thanks! I think so, too.

Aside from the additional knob to balance the mag and piezo pickups, mine has an un-attached bridge "holster" for the saddle, which both contains the piezo and enables the bridge to be adjusted (slightly) for intonation. The piezo wire comes up underneath it and the hole is oval so the wire can move with the bridge without getting pinched. My luthier created a little bit more travel in it as he was replacing the saddle to nail the intonation, which he really did.

I did a little customization on mine too.
