If you ever get a chance to try a Slo 100 you will hear an articulation of the gain structure that has zero fizz. Just note distinction.
The 5150 line all have way too much gain and gobs of compression which provides the opposite of not articulation.
They are fun to play through but the Slo 100 or BE deluxe 100 are a billion times better and closer to Marshalls without the shrill top end
The BE deluxe amps have a system volume and amazing master volumes that don't exist on other heads. Both my Slo 100 and Be deluxe were purchased used/mint so I did not pay anywhere near full price.
Add in real estate and overhead to be hand wired in the USA and with inflation the price is consistent with what Mike Soldano charged EVH in the early 90's
But as it has been said if you dig what you have rock on!!
