50+ years gigging, owned it all 2,3 4 times anyhow, went through two new marshall dsl40c's in 3 weeks. both quit so I'm not goin' that route again. wasn't totally in love with the tones anyway. after listening to almost every 6505 video on the net i thought i heard something other than metal in the amp. i was pretty sure I heard some classic rock, 80's hair band and saturated lead tones so I ordered one. UPS delivered it at 10am today. Even with a new speaker and oem tubes I am impressed. I knew the clean was not a strong point but I seldom ever play clean. I live in crunch land and saturated leadtones. 2 minutes of knob twisting and the green channel crunch is to die for. 2 more minutes and the red channel gives me my saturated 80's lead tone. I never use reverb so I can't tell you what the onboard reverb sounds like. I put my Zoom ms50g in the loop for delays only and it sounds just fine. I play 80's hairband and satch/via instrumentals and this 6505 delivers. The clean is ok for clean intros typical of the 80's, but just barely ok to my ears. I need to try it with a single coil strat later today and see what it sounds like. Don't know how well it takes od pedals 'cause I have no need for them with this amp. I've played it with volume on 1.5 and it does good at bedroom levels. If you turn it up for louder practice (2-3) it gets brighter and I take 1-2 off the treble. All in all I could not be happier. I LOVE the tight bass and I don't have any shrillness or fizz on the top end. It's a pretty neutral amp that I believe can be dialed in to a wide range of ears as long as you're not looking for fendery cleans. I'm gonna rest my ears for 2 hrs and go practice my set again.
