I’ve heard that the Arbiter Flats are surprisingly loud and would compete in volume with a standard acoustic kit, but I’ve never tried one myself. I would guess the Traps one is similar. I did have a Traps electric kit a few years ago and it was a pile of crap that fell apart at the first sign of a light breeze… I’d maybe look at the Arbiter one too as an option. They usually go on eBay for less than a ton too.
Yes like wise have tried both and they failed miserably! Good concept just poor build quality and replacement parts or upgrades-well!!! Left to be desired but wise after the event, just a shame that the manufactures don’t listen to the customers sometimes and if they put a bit more work into this area of drum product they could possibly have a nice little pockets of sales available to them.
