OK, so I researched this thing for 2 months and finally came up with the scratch back in the beginning of May. Units were to be delivered by the end of May. After many delays, I finally got my Motherload on Wednesday. I'm sure there are others out there. Let's hear your opinions. Day received-->My first impression? What a waste of money. I hooked up my Germino Lead 55 to it and ran my new EJ Strat into the amp. Listening through my Mackie HR 824s monitors and my AKG K240 headphones, I couldn't get over all of the fizz, mud, and tremendous compression. The guitar sound didn't react the same as when using a speaker cab. I guess it let's you hear how much of your sound is from the speakers and cab, including some distortion. I immediately emailed the company and have asked for a refund. Day 2-->My second impression? Wow, this is the best attenuator I've ever used. The wife and kid were away for a while, so with the same set up, I just used the attenuator section (Richter Control) of the Motherload. It goes from 0-2.5% of the amp power. Man did it sound great. No mud, unwanted compression, or fizz even at very, very low living room settings. Still no response to the email on a refund though. My third impression? Hmm, I am starting to be able to dial in some pretty huge and nice sounds on the bridge pickup of my Suhr Swamp Ash Classic, EJ Strat, Hamer P-90 Monaco Elite Goldtop, and PRS McCarty. Middle and neck pickups are still overly compressed, muddy, and fizzy at the same time when overdriving the amp. By now I've spent a good 5-6 hours with the speaker sim section. Lots of controls, but many aren't that effective at getting all the bad artifacts out. Too bad, 'cause I've really dialed in some seriously kick ass sounds on the bridge pickups of my guitars. Clean sounds are very impressive on all pickups though. If the unit was half the price, I'd keep it for the great sounds I can get. Still no response to my 2 calls today or second email sent for a refund. Anyone else?
