Caution: Long Vent Ahead Summary: Buy an Ampeg. I bought a Walkabout in March of this year from my local music shop, Music 6000 here in Oly. I was impressed with its tight, clear sound, volume, size and features such as the gain stage and DI output level control. I was also excited by buying a Mesa Boogie, a company that always had great products with a solid reputation for quality and craftsmanship. After three months of weekly rehearsal and occasional home recording (about 40 hours of playing time) the amp started to crackle after powering up. Occasionally it would drop out for a second but only in the first minute of play then it was fine. I attributed it to a warm up issue. Later I found that the speaker jacks in the back required a little jiggle in order to make the connection to the speaker cab. Eventually the amp cut out during play after having warmed up. Having read about bad jacks I took the amp to where I bought it hoping for a replacement. Since the amp had been sold 90 days prior they were reluctant to replace it , instead they told me they would look at it, fix the problem and if there were any more problems they would replace it. So they replaced the input jacks in the effects loops claiming that a failure here would break the circuit and explain the speaker outputs cutting out. I was really angry at this point, I felt the failure of the input jacks was an indicator of poor quality and I expected more from Mesa. I thought about writing a letter to the company you know, I work hard for my money, what would it cost to use higher quality jacks, etc.. With the repaired unit I set up for rehearsal the following Wed. Heres the chain of events: Plugged everything in, set up my compressor through the effects loop, ran chorus and tuner in through the front input (due to power supply issues) Turned it on, got tone for a second Volume dropped to nearly nothing and then just a low level super buzzy distorted tone The amp POPPED And then emitted a single unwavering tone and got stinky. I shut it all down and declared time of death. Fortunately the singer had his Ampeg SVT Pro III on hand for me to try out as he was getting ready to sell it and he wanted it tested. So I played through practice on the Ampeg and it sounded 100% better than the Mesa ever did with all the power and better control. The next day Music 6000 said they would replace the Walkabout or let me swap it out for anything in the store. I tried some SWRs and liked those but not as much as the Ampeg. Kudos to M6K for doing the right thing and devoting time to me to set things right. I decided to just get my money back and try something else. I went to Bass Northwest - told the guy I really liked the SVT III and a friend was selling his for $500. The sales guy proceeded to go on and on about the SVT III further convincing me that I should buy the used one. So then I went to Guitar Center by the Space Needle where they had all the SVTs in a rack with all the Ampeg speaker cabs A/B-ed around an isolated room. I checked all the SVTs and like the III the best even over the all tube 1000 watt SVT IV. The moral of the story is this: Buy an Ampeg.
