Congrats!
Regarding the "boomy" tone, may I ask how you have the EQ set on the bass?
You may already know/understand this, so my apologies in advance, and I mean no offense. The Elemental has a bit of an odd setup in that the high and low eq are boost-ONLY. That means that "flat" is all the way "back" or fully counter-clockwise. If both EQ knobs are rolled midway up, or all the way up (fully clockwise) then the highs and lows are boosted significantly, which consequentially buries the mids that are so important to note definition and clarity. Notice that on the EQ knobs' rotation, there is no "center detent" to indicate "flat."
I played mine in a rock band setting over the weekend and just today got to listen to some GoPro recordings our guitar player took. I played the bass itself with both pickups on full with the EQs on the bass completely flat, and at the ToneHammer 500 I added just a little low and low mids, and cut some treble. Sounded great, and I didn't have to crank the volume to be present in the mix. Just level-matching and G2G.
You are right that it can have a massive low end, though! With the lows boosted, a pro-level friend of mine commented "Wow, that sounds a lot like some old Ken Smith action right there! So thick and meaty!" But with the lows flat/off, that side of things doesn't really come out too much for me.
Thank you for the insight but the EQ knobs were already set to flat. It is not a problem though, it means that it is a bass with its own sound signature, very different from my Blacktop Jazz Bass and my Ltd AP-4 that, in my opinion, already have a lot of personality.
I mainly use my basses to record music with a lot of synths, guitars, drum machines, effects, so the mixes can get very busy. I prefer to record the bass directly in a DI box, so I don't use amps any more, but I have a Tech21 VT Bass that can tame the low and bring more mids, and I still have the possibility to use a VST plugin to sculpt the sound.
More importantly it is an instrument that inspires me to play more or different things. It's difficult to explain but it is so ergonomic, so easy to play that I concentrate on what I play currently.
