With the right pedal (or even just a good EQ pedal) I wonder whether you could get excellent surf music tones out of your DV Mark Jazz amp. Are you truly focused on getting the sound you need, or are you actually just looking for an excuse to buy another amp? No shade-throwing intended....I've succumbed to GAS plenty of times myself. But DV Mark amps are extremely high quality and for very little money the one you already own might get you exactly where you want to be.Cheers, I had not considered the Tonemaster, or any digital amps for a long time, though it sounds like the technology might have improved. The neodymium speaker is appealing for its weight as I have one of these in my DV Mark Jazz amp and the whole combo weighs only 10KG! New these are a bit over my budget here but I will give this some thought.
