Ok let me offer my 2 cents on the BG250-115. 1st, a bit of background about me as a point of reference. I've played bass for about 20+ years mostly in studio settings along with a few live gigs along the way. I also play guitar and saxophone. I'm not a full time pro nor anything close to God's gift to the low end. That said, I can very easy handle a full nights worth of tunes in most popular styles.
Alright let's talk amp
Pros... Good power and crisp tone. Should be enough power for just about any situation. Really if you need more, you're gonna want to run through a PA anyway and the TC will make for a perfect stage monitor and tone sculptor. The amp sound opens up nicely as the master gain climbs greater than about a 4 setting. The 15 inch speaker puts out a sweet rumble. There's an overall balanced crispness in the mids and highs along with low end punch at a flat EQ setting. The EQ offers the ability to dial up plenty of different tones. It's pretty surprising what you get with just 3 bands. Very happy with that. The effects and Toneprint slots are impressive. The spectracomp, flanger, and doubler are worthy of the price admission. Lastly, the amp is very quiet without any discernible noise.
Cons... I'm having a hard time believing this amp weighs just 35lbs. Maybe I'm getting old, but it feels about 5-10lbs heavier. My 3 year old son is about 35lbs and I carry him around everyday. This amp defiantly weighs more. Anybody got a scale I can borrow?

Also, I can't understand the lack of an effects loop placed between the Toneprint effects slots and the master output section. Seems to me, the spectracomp would be nicely sitting in front of a pedal board with chorus, flange, autowah, or whatever. Lastly, the amp tends to get boomy when sitting directly on the floor. So, isolating the amp with a stand or isolation riser is a must IMO.
BONUS. The amp came with a rebate deal where you mail in for free ditto looper.
I'm real happy with the BG250 so far. I'm plenty confident it'll meet my needs for the new band I just joined. The band has live drums and two guitars playing through smallish combo amps. One guitarist doubles on keys and sings. The practice volume is moderately loud, but not obnoxious. The set list includes classic rock, funk, soul, Motown, and modern rock from the '60's through current stuff. 1st gig is next month. As long as I can cut it, I'm sure the amp will too
