After years (decades) of occasionally trying various Fender bass amps, I was really surprised to hear the great tones out of the Rumble 500 Combo amp. It is 350 Watts, so don't let that name or even Fender's advertising fool you. It is only 500 Watts with an extension cab. Anyway, after years of Fender bass amps making the basses sound like the AMP like those old BXR units, I feel this amp with it's fairly even EQ and sound lets the BASSES SOUND LIKE THE BASSES. A Jazz Bass sounds like it should. Precision Basses sound like they should. Stingrays sound like they should. I own all of these. It is a fairly transparent bass amp sound, relative to previous Fender units, and needs no further disclaimers.
The Rumble 500 is a 2X10 with tweeter (with on/off switch) and weighs only 38 pounds. You're using IEMS now, but in every situation you might encounter, that's not guaranteed. This amp is small enough, light enough, powerful enough, I don't worry about volume or headroom in the kinds of situations I encounter, which are greatly varied.
Also, it's about $650. You can spend more on higher-end, or more near-boutique, or boutique amps, but after 4 years, and ability to buy those things and gig with them, I see no reason to buy anything else, and my Bag End/Alembic/Crest Audio boutique stuff (unfortunately) literally sits in a closet right now as it has for years. And also I don't have to move that 150 pounds of gear, period. Compared to this rig, the Fender certainly qualifies as "small". I know bass amp tone, and my Fender is not only "good enough" I'd say it is very good, and it makes me want to play more. My gigging life as a bass player has become SO much easier.
If you don't end up buying the Fender I recommend, I'd be interested in seeing if what you bought was in any way lighter, sounds better and is less expensive. I can't imagine or have any marketplace product knowledge of any one thing beating this Fender on all three purchasing requirements. I guess I should watch this space and check about in a few weeks or a month.
