Politics aside.... The Legacy amps don't sound "Legacy" from what I experienced. They sound somewhat vanilla and lack the throatiness of the RB series. They sound modern with a less than grunty distortion circuit.
"Boost" - really had/has something special in the RB line.
The other 2 new GK class D amps are already modern and super flexible from the looks of it.... the "Legacy" should have been more simple with a meatier tone. YMMV.
Yes, YMMV - mine certainly does! I needed to pick up a new amp quickly when my #1 went down during a long run of money gigs last week.
Sweetwater was able to get me a Legacy 800 in a little over 48 hours, and I hustled it into service just in time for the hit last night. I'm very impressed, both with their service and with the amp.
I played an 800RB for many years, and have owned and loved a couple of MB's in the many years since. The MB's are a great tone (reminiscent to me of my long-gone 400RB) but different from the 800RB entirely.
Sound check took a little doing as I adjusted to the L800's somewhat different gain/master relationship (every GK model's been a little different in that regard, IME). I found myself setting gain higher than on the MB's, but I sorted that out pretty quickly, and discovered the 800 watt headroom once I played with the master a bit. Be aware though, it's not a significant volume increase from the MB500 or MBF 500, but just a little extra horsepower. I've also gigged an MB800 but I can't really compare it to that - I'll need more time to explore its outer limits.
It took no time at all to get the GK tone through the EQ. Even though the controls are re-arranged in a less-GK and more conventional fashion, the tone-stack settings for me work pretty much the same as any time I encounter a GK amp - very easy to get the sound I hoped for.
After sound check I played with the foot-switchable distortion feature and was quickly able to find a setting that very much resembled the old 800RB "boost" function, and also the B-channel function on the Fusion preamp. To be honest, having 3 controls vs a simple "boost" makes the Legacy actually very versatile in the overdrive department. Not only was I able to control the volume level of the B-setting using the "Level control" (like the old "Boost" knob), but the "Depth" and "Edge" controls allowed more shaping of the B-sound than any earlier GK products I've played. For those who hate overdrive through a tweeter, the "Edge" control allows you to find a sweet spot that eliminates harshness altogether. Bravo for listening to players, GK!
As the night went on, the touch-sensitive nature of the amp revealed itself - it became more and more like its 800RB ancestor as I got to know it better. I ended the night with nothing but a big smile and compliments from the sound tech and others. As I said to them, "it sounds like my old amp, just like I hoped it would".
I've never spent much time with a 700 or 1001 or other GK products except for my 400, but for those who've hoped to recapture the feel and sound of the old 800 with a bit more headroom, there's hope here, IMO.
Oh, and it fit perfectly into the laptop bag I've used for the MB amps for years - it fit better, actually! It's chubby shape filled out the space nicely!
I'm very happy after one gig and hoping the honeymoon lasts! Tom
