It's been a while since I've touched 'bass' on my foray into DB (haughty laugh). It occurred to me that after some initial tweaking of my Shadow RB preamp I rarely have had to touch the thing--other than to adjust the volume--so I thought I might share my settings. See the attached pic from Saturday's gig. And a brief long-term review to follow below.
I will occasionally still tweak the Bass knob a bit, but that's about it.
The only feedback issues I have are if the acoustic guitar is too hot in the monitors. it happens so rarely that I usually forget what the cause is! It causes the D notes to wolf howl a bit.
Battery life is good. I would say the advertised 150 hours is not unheard of.
I don't like the decimal point (#21 in your SRB Pro Manual) that indicates a half step. I have missed it twice and gone into a set tuned a half step off. The angle is bad--you really have to lean the bass back to make sure you see it.
Anyway attached is a pic of my settings. It sounds good to my ears. We rarely play with a soundman, but when we do I usually get comments on how good it sounds. I use the same amp settings on my Fender Rumble 200 as I do for my Stingray 5 (Maybe I should have taken a pic of that--hmm. I'm doing a bit of low mid cutting on that--IIRC). I usually adjust the amp based on the Stingray, then the DB sounds pretty good too. I just use a Fender passive A/B switch between the 2 basses.
I have not done any feedback abatement to the bass, FYI--no foam, no double sound post, no balloons, no f-hole covers, etc.
I'm not playing any rockabilly really, but some country slap stuff has been sounding good--some Hank 3, Honky Tonk Nighttime Man by Merle sounds good with some slap thrown in, Etcetera and so forth.
I feel like my technique has elevated sufficiently to do a credible job on the double slaps. I'm not playing enough to really worry about triples or too much advanced stuff. I'm only playing it on maybe 12 to 15 songs, and we only gig 6 or 7 times a month.
The Shadow RB Pro has held up well on my CCB, el-cheapo bass. I can't imagine even a full-time pro with good gear needing much more, lol! YMMV
Just sharing this as a measure of thanks/paying forward for all the startup assistance I got here on TB!!
