After playing both back to back several times, the Dingwall ALWAS has the edge in my honest opinion. And the Dingwall being used is the passive only DROC standard 5. So I have thought about this for a while of what is holding back the Ibanez BTB 805/806 multiscale basses. They have the same 37 scale B string, but the G and C strings sound thinner because of being slightly different than the Dingwall basses. The Ibanez has stainless steel frets. Well, my theory is that those banjo and mandolin frets on Dingwalls somehow contribute to part of the tone on those basses. I’ve noticed it when doing slides. It can come close to giving fretless vibes. I’ve noticed that stainless steel or not, there have been a lot of folks complaining about fret sprout with the Ibanez. Probably a fairly easy fix. Finally I have to ask this question. If the BTB had an 18v preamp instead of 9, would it make a substantial difference in the bass? Dingwalls use 18v for their active basses that can be used in passive mode. I used the BTB on a 210 combo amp that was putting out maybe 300 watts at full potential in 8 ohm mode without the extension cabinet and felt quite underwhelmed. I plugged the Dingwall into it and it immediately seemed to have a lot more presence. Both basses shine through a 410 or greater rig. Just my observations. Doesn’t mean I’m right about any of this.
