The Marshall MB450H is a powerhouse amp head for your bass. It wallops a massive 450W of total bass power when connected to 2 extension cabinets. All that's left to do now is to choose your preferred choice of cabinets so you can plug in and rock!

Both channels--Modern and Classic--have separate EQ. The Modern channel features bass, treble, parametric mid and a compressor. The Classic channel with its ECC83 preamp valve includes a Boost switch, and it has a 3-band passive tone network with 3 different voices. Like the high-wattage Marshall combo amps, the MB450 bass head has the option of blending the 2 channels either from the front panel or via a supplied 2-way footswitch.

Power for the price

By Robin Hobbs

from PCB, Fl.

I played combo amps for close to 30 years before deciding on spending the green for a more professional looking and sounding package. In 2011, I purchased the MB450H along with the MBC410 and MBC115 cabinets and it all stacked nicely. After plugging it all together and plugging in my '77 Rickenbacker 4001, I knew with the first stroke of the strings, it was money WELL spent! I hope this head and the afore mentioned cabinets will be made available in mass.

I rented this unit and was sorely disappointed

By Steve

from Louisville, KY

The sound was great. It had absolutely no punch on the low end, as my band mates vigorously complained. If I'm not punching them in the chest with a sonic low-end fist, I'm not doing something right. Surprisingly, my damaged GK Backline 300 (only one working channel) seriously kicked this unit's butt. If you play hard rock and require a low end punch, this isn't the unit for you.

MB-450 Kills

By Karl Ritterpusch

from Perry Hall,MD

I've been an Ampeg all tube guy my whole life and never considered using anything else. Then I decided I wanted a channel switchable amp for live situations. I tried out everything I could get my hands on and the MB-450H blew them all away. I play in an 80's metal cover band and this thing couldn't be any more perfect. You can get a tight mid range push with the modern channel and then switch to the classic channel for the tube driven bottom end Steve Harris sound. You can accomplish this via the foot switch which is included. Then hit the boost button and crank up the gain knob and you have the Geezer Butler distortion. All of that and it's not even that expensive. Buy it !!

Great for experienced player

By Sasquatch

from Houston,tx

This is an amazing amp .. if you are serious than spend the money without even thinking. but for a starter wait and just get a practice amp cause it will give you time later to think about the style you want and if you really want to keep playing. but i am using this amp for shows and its amazing. it has a great sound and you cant beat the power. i have played on several bass amps and i cant find one i love more. and who can beat that Marshall classic sound.
