those are amazing looking and I love the straps!
Thank you. The ones on the ends (my #1 and #2 basses) are Ethos Custom straps from their Stars and Stripes line and the two in the middle are Anthology Gear straps. Super nice straps overall.
I did pull the cover and see that it is the standard MK-1 preamp so while I haven't messed a ton with tone settings (everything flat), my guess is the treble will sound fairly brittle when I turn it up but as I'm not a slapper and prefer mids over highs, I may not care a whole lot. Although, I DO think I have an Aguilar OBP-3 pre hanging around here somewhere if I get the hankering to do some mods.
