My first impressions....
Wow, Seymour Duncan knocked it out of the part with this pedal. What a fantastic overdrive. Super super versatile. Great for studio - for live, I'd probably need like 5 because I wouldn't suggest tweaking the Drive button or the EQ with your toes.
For the sounds below, you'll hear the woofy tone as the dry elevenrack plexi-ish tone I use on my lighter stuff first.
The second, heavier tone is the heavy patch I use from the 11r. I haven't used the 6505 yet but later this week I will.https://soundcloud.com/romeroenr/sd805
