Killer Kit - Best Amp Ever?
The 5F6-A Bassman's rep as one of the best amplifier designs ever made is well deserved. Try as I might to find its shortcomings, as I can with so many other Fender and other designs, I just can't. It's perfect. The perfect design and the perfect sound. While perhaps being too large and loud to get over drive at reasonable volume, the overdrive is pure rock nirvana and the cleans a spanky clear. Mojo does the amp justice. Correct parts, all of high quality, including correct transformers. I dare say this is their best kit. Now strap on your techno-geek helmets because I'm about to nerd out (just picture me pushing my taped horned rims up on my nose as I say this to you) but - the Bassman can be man different amps. First there was the 5F6 - notable mostly because it had a second gain stage (basically a 25uf cap which you will see is deleted on the 5F6-A layout). This cap adds mondo gain. It's a simple swap - so add one to your order. Most importantly - this kit is supplied with Audio Taper pots. The Bassman only used an audio taper on the bass control - the rest had the faster taper of a Linear Pot. This is not a subtle point. It's night and day - add some Alpha Linear pots to your order as well. Now the 5F6-A as drawn on the layout is said almost not to exist in real life - or if so few examples have ever surfaced. As drawn you will have a mid heavy amp that is very much in the Hendrix vein. It should be because Marshall copied this circuit as we all know. Most 5F6-A Bassman had a different middle and bass cap value (.02 and .1 respectively) as well as a 100K slope Resistor. As well as a 6.8K tail Resistor to replace the 10K on the negative feedback loop (will increase gain slightly). The Presence control also used a 25K linear pot and a 4.7K Resistor to ground (this is not that important a change I don't think). I will leave it to you as to determine where these parts go but I will tell you, should you want to hear the different voices the Bassman had to offer, historically - it gives you the option of deciding which you like best as well as gives you the chance to mix things up now and then when the mood strikes. All in all a great quality kit from Mojo. They always stand behind their products and are always interested in how to improve them. No affiliation - just a happy customer. Now back to playing my Mojo Bassman! Just had to pause to write how great it is.

I bought the amp built by Mojo. Build quality was first rate. The amp fired right up and sounds glorious. Great amp. As good or better than any other amp of this type that I've tried and I've tried quite a few. I highly recommend it.

I recently built the Bassman Tweed kit and it is fabulous. Everyone who has heard this amp is blown away. Everything about this kit is absolutely first rate -- the cabinet, chassis, components, etc. I couldn't be happier!
