This is just a amp shootout i did for myself and the "test" results. I just thought i would share how it went and my personal thoughts. So here are the results from the shoot out. Ill give you the numbers first then my notes and thoughts. The test was done on a 1-5 scale, 5 being best. A number of zero was given if the amp failed to get a grindy/distorted type tone. (A feature I was looking for highly) Eight basses were used for this shootout and the cab i used was my BNA Bassic 115. The basses used: (Buy the way its kind of a bass shootout too By taking the number of how much I liked the bass thru the amp, I then added them up for the basses total number ) 70s aria Ripper clone--22 79 white Ric--24 White Parts P bass--27 74 Fender P bass--30 Parts Jazz Bass--27 Early 90s Musicman Stingray--20 78 Brown Ric--36 Black Parts P/J bass--25 In order from best sounding to worst sounding Best clean amp: Genz Benz Shuttlemax 9.2--33 Gallien Kruger MB500--30 Genz Benz Shuttle 9.0--30 Gallien Kruger 800rb--29 Orange TB500--23 Best Dirty/Grind Amp Mb500--26 TB500--21 800rb--19 9.2--0 9.0-0 This test took ruffly 4+ hours to do. I didnt do a terrible amount of knob turning. I started by setting the volume/gain and EQ at noon then running the basses thru it. I then found a setting I really liked (using either the 74 or 78 bass) and played all the basses thru that amp again. I then tried to make the amp distort (As best as possible) and played all the basses thru it a third time. Now the notes I made during the test in no particular order. --The TB bass does sound like a tube-ish amp when its breaking up at the full gain setting. --The TB almost sounds the same no matter what bass is plugged in, clean and dirty settings. Its tone colors your sound quite a bit and clean it almost sounds like a blanket is over your cab/tone. --mb500 sounded as loud as the 9.0 with all controls at noon. --9.2 wins for volume and tone over the 9.0 --i prefered the FET channel on the 9.2 over the tube channel. These are the over all winners (total scores) mb500--56 800rb--48 tb500--44 9.2--33 9.0--30 So all said and done my favorite bass is my 78 Walnut Rickenbacker and the Winner of the Shootout was the GK MB500. The next day I played with the top amps again and the results didnt change in my ear much. I really liked the GKs over all. The GKs (after a very short test) took distortion pedals the best. Over all i had high hopes for the 9.2 winning the day, but the top 2 slots are held by GK. Thanks for reading.
