Feature:
The only improvement I can think of would be an Ebony fret board. Also, shielding around on-board contols. Maybe a flip up for the 9 volt battery.With an amp set flat I can dial in any tone I want from blues to funk to metal.It's my favorite bass,ahead of Carvin Pedulla,Ibanez& Charvel.The B-304 is BEAUTIFUL tone & looks!!

Quality:
Quality control is excellent the paint job is beautiful with gold-plated contol knobs,bridge and keys.The neck holds true in hot or cold weather, she will stay in tune all nite long.

Value:
For it's price range no bass out there even comes close. I spent 3 days and 8 music stores until I found the B-304,and saved money

Desirability:
Great feel and great tone, the first time I played live the girls thought it was hot and the guys kept saying that's a ESP Korean made?

Sound:
The B-304 with 24 frets thru the body neck, thru the body strings active EMG w/ onboard high,mid,&bass controls.Looks and sounds great She will slap & pop,drop D tunings-no problem,. To get this same quality for on an American made bass (like my Pedulla) would cost an easy $2000.00 or more. Also lightweight and very user-friendly get it today!!!!!!!

Support:
No problemos Amigos.

Overall:
The only upgrade I intend to make is to add a brass nut.If I wear out the fretboard,I will replace the rosewood with ebony.I get everything Iwant and need out of my LTD,and have money left over for other accessories.

Feature:
Built in effects are very nice. they allow me to make the sound whatever i wish.

Quality:
The product was put together well and seems to be sturdy...one problem is some of the fret markers are a little worn away. I have a backup bass but not because i'm afraid this one will break, is just the "other one" i have from before m purchase

Value:
Yes

Desirability:
This bass guitar not only plays very well but it has looks to put others to shame. I feel sexy just holding it.

Sound:
The ESP B-204FM is amazing, i've been jamming on it for a week and it continues to impress me. I am using a Fender BXR 300C amp and they compliment each other well.

Support:
didn't need to contact the company

Overall:
I will have this product for quite a while before i search. This bass guitar is one of the only i considered in my search do to it's look and price, i had tested it in a store but the price was too high. If this product was stolen or lost i would search for it, then if nothing came up i would replace it with a similar, possibly same, bass. I like the great sound and tone it produces along with its great look.

Feature:
Very well built, low priced bass. Solid and feels natural to play.

Quality:
The layered neck transmits well, the controls are solid and feel like they're very good quality. The machine head is solid, all the pegs operate cleanly and with ease.

Value:
All in all, the B-204 is a great value for the price.

Desirability:
Really sweet bass.

Sound:
Very customizable sound range. I've been out of the business for 26 years and had to sell my Jazzbass years back. I have been able to recreate the exact sound with this guitar.

Support:
Have not used them yet. Warranty seems good though.

Overall:
I don't know if I'll catch the bug again or not, I really missed the business but this bass seemed to be a great startup point for me again. I had an old Fender Jazz Bass originally and never thought I'd be able to replace it but the B-204 has the right sound and action for me.
