Random Thoughts....
I think one of the reasons I'm going BACK to a WW Ultra is because I haven't been able to get my tone or punch with any of these newer micros. I was always amazed that I could pretty much set everything flat and get a great tone. Only little tweaks were required for different rooms, etc. My cabs have been a pair of 210s - at first a pair of Goliath Jr IIIs - currently a DIY set built to SWR dimensions with Delta 10s - and my main bass is a pre-Gibson Tobias Killer B5. Most of the time, I can just dial in more or less lows, mids, highs on the bass with the Bartolini preamp, leaving the amp flat. I have the same concerns as some have mentioned about how much longer Walter will be making and servicing amps, but based on the one that I had for over 10 years, it only had one problem that required me to send it to him and he fixed it in a couple days. I haven't spoken to him in a few years, but when I get this Ultra next week, I'm going to call him with the serial # and ask a few questions like when is he going to retire and are his amps serviceable by others. I know his answer is no while he's still in business and he gets pissed if someone else messes with the amps. When you do get him on the phone, he usually talks a lot and is quite nice. It will be a drag when he finally retires and stops building amps. I don't think there's anybody in line to take over the business. I think it's just something he started doing with all his knowledge of electronics and it was better than working a regular job for sure.
