Love/hate with my 6505+

[jinch0]

..... some days I want to get rid of it and some days I love the tone. Are they any mods I can do to improve it or just sell it. I feel that the 5150 I had sounded better.

Sent mine to Jerry at FJA Mods. Very happy I did.

Get a 6505/5150 then. You'll even make a bit of money

i personally like the 5150 better than the +, or the II. to me it was smoother, bigger, and more aggressive at the same time.. had both years ago and kept the 1rst series. there's both camps on this, and alot of people prefer the higher midrange, and the controls of the II, or +. you could probably trade someone pretty easily..

There is a tech that it's going to charge me $60 for the bias mod so i'm going give it a shot

Don't these amps have a bias trim pot already? At least mine had one... maybe not so on the earlier models

 

[jinch0]

I haven't check where is it?

There should be a pot on the back if I remember correctly. It's been 10 years since I had that amp though .

I always feel that way with any amp i cant bias. I could mod it now but back in the day I had a Mark III. some days were killer some were not. weird.

6505+'s have a bias potentiometer in the back right corner. The range is limited though - it wont be enough to take the tubes out of crossover.

I owned both a 5150 and 5150 II at the same time. I kept the 5150 II at the end of the day for a few reasons. Less gain/compression, better clean channel, independent resonance and presence controls on the crunch and lead channels, and the tonality did not change as drastically from tube change to tube change. I would get it dialed in to where i liked it and before long it was time to retube the preamp or replace a microphonic preamp tube. It just got old. the 6505+/5150 II's are much better about this simply because you have more control over which tubes benefit which channels most effectively making preamp tube swaps less dependent on one another for clean/crunch/lead control and with independent EQ's you can make the most of it without much hastle at all.

I think what you are experiencing is just the nature of tube amps. Some days great, others not so much. That's been my experience with every tube amp I have ever owned. Lots of variables day to day with tube amps. Touchy little bitches they are.

but ive personally never had it with marshall or marshall type circuits

I personally think it's in the mind and that you hear things different from day to day.

I think ear fatigue and different rooms can play a big part, but I've noticed changes in my guitar room in the tone with changes in humidity, different times of day (electrical), etc.

Agreed, my Marshall's always put a smile on my face!!

My jmp is still a tempermental bitch some days, depending on how hard or loud i play, or how its feeling lol. Some days it just needs a little nudge, and some days it needs a good bit of boost to get it rollin'. The 5150's always sounded better in a band mix, and need to be cranked up to sound right. Mine were always particular about pups too

+1 on this
I've had the 6505+ and then bought the 5150. The 5150 was a lot rawer, in your face and I would swear mine even had a better clean channel than the 6505+ which even has a dedicated EQ for that
