For what I do and the folks I play with I'd say in no particular ranking (and this is just bass amps) I'd have to have Eden, GK, Markbass. These are brands that are readily available in shops and online. Having said that I personally now use a Tecamp Puma 500 (just happen to have the funds at the time) and my main backup is an old Trace Elliot GPSM 7 300. Behind that I have an older but in new condition SWR Working Man's 4004. It seems the Trace will never die. Mad Punch for days. I keep it and a 2x10 in the trunk of my car, just in case

The tecamp is clean, clear with a nice low mid bump. Not really HiFi, not really warm. It's a gigging amp and will let you cut through the mix due to it's voicing. I'm not going to even say it's the best but when you play through it, you know you're playing through a quality amp.
If I had to, Carvin, Genz Benz, Aguilar (every body and their mother has one it seems).
or even a Kustom KXB-500 (mo watts fo the money in this one). If I had the money Thunderfunk, Walter Woods, or a some outrageously clean power amp with a nice expensive Bass Preamp. I played through a Walter Woods head once and an old SWR Goliath III 4x10 and was just smiling my azz off the whole time I played.
