measured it at 21mm at the 1st fret. Not sure if these quick shots will give an idea of the profile.

It really is amazing how these things go. i actually had a USA Lakland JO which had the best neck i ever played and sold it as i didn't 'love' it.. makes no sense, but it is what it is. The Moon is giving me a buzz in these early days of owning it. Not sure I got that from the Lakland. I'll measure the depth of the neck at the 1st fret later. My 'Bat' description is really about the roundness and depth of the C profile. It's why the guy i got it from sold it! Maybe @jay-syncro can chime in. A newer JB4 might have a different profile altogether

I just landed a 1998 JB4A, which may not be what you are asking about, but I can add that, blimey it's killer. @BlueMoon is indeed correct about the weight. mine is ash bodied and weights a tonne.. well 5.2kg but it´s weighty. Fortunately for me, I don´t mind a heavy bass. Mine has the Bartolini 9s pups and the NTCT Bart pre amp. It's made for slap (with its mid cut), but mids can be boosted from the board, and finger style, it's warm and fat. Quality in every aspect. But the neck is also fat. It has a full C (jazz width) profile and feels like a slender bass ball bat. Very similar the BB in the picture in fact. Here again, lucky for me I like em fat, thin, wide or narrow.. Maybe newer Moons have a sallower profile?

This has likely surfaced before, but anyway, a seldom direct comparison.. Which one has it for you?

Be sure to drop some pics 👍

Yes, the pre amp from the Thunderfunk drives the Sumo much better, but same issue exists, the cabs become overloaded before they get loud enough. This is the original enquiry I had.. Wondering technically why, as my Thunderfunk drives the same cabs way louder without any complaint

Drums is drums

THe VT1 has input level, gain and output level. The input (i read) is to compensate for output level of the Bass, active/passive etc. I have that pushed past noon, the gain similar (just a touch of break up) and the output cranked), but to answer your questions, the Sumo could be pushed a lot harder. The pre amp out from my Thunderfunk drives the Sumo much harder, but I still see the same issue where Cabs are overloaded before I reach volume I need to cover the Band. The thunderfunk, needless to say is ample. It drives the same speakers to easily loud enough without any complaints from the cabs

I'm running theVT1 into the Sumo, then into both cabs daisy chained. Had another rehearsal last night. I drove the VT1 quite hot (output) and the Sumo just about managed rehearsal volume beforte it distorted the cabs. I reckon i'm at about 7 on the volume dial of the Sumo. I have tried the pre amp out from the thunderfunk where I usually run the gain at around 6 or 7. Tnat really gave the Sumo some umph, but again, it was killing the cabs. Had to turn down to just below rehearsal levels..

Anyone fancy educating me..? I bought A Sumo monster on a whim really. I'm going through a rationalisation of my gear, basically selling stuff etc, and then pops up a Sumo monster for reasonable money. I've been hanging on to Dave Hall VT1 pro and i thought, hang on.. Power amp.. pre amp.. i'll have a dabble. The VT1 is a killer pre-amp, but not what this is about. I run a couple of TKS 1126s which are really great, but have a rather low sensitivity. My gear selling left me with my ThunderFunk 550 to run these sweethearts, which it does magnificently well. The TKSs are rated at 250 - 600w at 8 ohms So i assumed the Sumo's 1200 class D watts would be mega, and i'd need to be careful with the master volume etc.. What i actually found is that the Sumo caused me to overdrive the speakers (farts and crackles... not good) long before I reached rehearsal volumes? The Thunderfunk is much 'louder' in perceived volume and doesn't kill the speakers. So whats going on? Why is the Sumo not delivering volume? .....Sounds mega though , that VT1 really is a colourful little fellow
