Please read our article 'Mojotone Amp Kit Building Primer' along with our amp kit disclaimer located in the Specs tab before buying this kit.


Mojotone’s Tweed Super Style Amp Kit is based on the ~20-30 watt model rumored to be one of Leo Fender’s favorite creations. The Tweed Super’s design gave it a more nasal sound than some of its larger relatives, which makes it popular among guitarists who play gritty blues and rockabilly. This 5F4 circuit has a unique break up that has been featured in recordings by the likes of Joe Bonamassa and The Eagles.

 

The amp utilizes two 6L6gc power tubes for to push 28 watts before clipping, all the while delivering fat luscious low tones with pristine highs. We paired the Super circuit with two Jensen C10Q 35 Watt speakers that are lively with a fat, snappy response and offer a cool gritty overdriven sound that will not sacrifice articulation for distortion. For those players seeking a responsive amp that is perfect for roots rock styles and is easy to haul around, the Mojotone Tweed Super Style kit is a no brainer.

 

Global controls include presence, bass, and treble for a multitude of sonic variations. There are two channels, bright and normal, and each has two inputs. The normal channel is more tame with a slightly warmer overall sound, while the bright channel has more aggressive highs and breaks up slightly faster. These inputs can not only be used in a traditional fashion but can also be ‘jumpered’ together and blended, via their dedicated volume controls, for even more sound options.


Please note that there is no step-by-step assembly manual available for this amp kit. This amp kit comes only with a technical schematic and a wiring diagram. This is an advanced kit best suited for builders with previous amp building experience and understanding of electrical circuits. We do offer this amp kit fully assembled by Mojotone for an additional fee (Assembled option located in AMP KIT OPTIONS drop down box above).

Disclaimer: Some of the parts contained in this kit are subject to availability.

Mojotone reserves the right to change or substitute any and all of the parts contained in this amplifier kit without advertisement or notification to the buyer. Part substitutions made by Mojotone are guaranteed not to affect the integrity or operation of your amplifier kit. Time estimates listed are from start to finish. If you are new to tube amplifiers, additional time may need to be factored.


When purchasing a kit from Mojotone, you will receive the following documentation.

1. Schematic

2. Wiring Diagram / Layout

Our beginner level kits such as the tweed champ and tweed deluxe include a manual. If you purchase a kit from Mojotone and do not receive these documents, you can obtain copies by emailing tech@mojotone.com or calling 800-927-6656. The Mojotone staff is available Monday through Friday from 8:30 a.m. to 5:00 p.m. EST unless otherwise closed.


Mojotone kits include the best quality parts that are available at the time of purchase. If a substitution is required, our team will use parts that are of equal quality to ensure the integrity of the kit build remains the same.


Building a fully functional amplifier kit is not an easy task. Before building a kit, one should have the ability to properly solder as well as read and understand a schematic and wiring diagram. While we do our very best to ensure all documentation is current, the included documentation is meant to serve as an overall guide to building the amplifier. Simply following the schematic and wiring diagram does not guarantee you will have a fully functional amplifier. In fact, post build troubleshooting is a common issue across all builds.


Our staff is available to assist with basic troubleshooting needs. There are plenty of online videos available that are helpful with most post build issues. Technical staff is available via email by sending a message to tech@mojotone.com. You may also call our sales team to discuss build problems, dial 800-927-6656 and press 1 for sales.


Building a tube amplifier takes time, dedication, resources and most importantly... Skills! The experience of building an amp can come with some frustration, the reward of completing the build is definitely well worth your time. Please review the wiring diagram, schematic and manual (if applicable) prior to making your purchase. Mojotone will not accept any returns on amplifier kits and/or parts that have been assembled, soldered or modified.

Great kit,building it was easy and enjoyable.

Great kit,building it was easy and enjoyable.

40 watts RMS: With one simple mod and the addition of a larger filter capacitor & JJ 6L6GC tubes my super "Super" amp puts out 40 watts RMS, as tested with a signal generator and an oscilloscope.

The mod: Connect the red wire (centertap) of the output transformer to the load side of the standby switch. Also, replace the 16uf cap on the load side of the standby switch with a 47uf/500v cap.

This mod makes the choke feed all of the DC circuits EXCEPT for the 6L6 plate circuits. (That is the way the blackface Fender amps are wired.)

I installed a 50 watt output transformer to make sure that addition power gets to the speakers.

I think I've got an amp to last me a lifetime.

This is the 3rd or 4th 5F4 I've put together. They all had Mojotone cabinets, but this is the first "kit" I've put together from Mojotone parts. All in all, a great kit, and a great amp.

I added a few items such as star washers for the jacks, and a copper grounding plate (Hobby Lobby!). I did have a few really small issues (wrong tubes, damaged transformer) which Mojotone handled super fast and effortlessly.

The kit included adequate lengths of wire to get it all connected up. The instructions are... for the experienced builder, unfortunately. Not a beginners kit - unless - they're also studying some assembly tricks online or in a good "amp book". I did like the way Mojotone compartmentalized all the resistors and capacitors, instead of just putting it all in a bag. VERY NICE TOUCH! Just look at the label, check the code on the part, and install. No rummaging around like doin' a jigsaw puzzle!

I also added my own little secret circuit change, that does not change the great tones from the preamp, but does up the gain into the cathodyne phase inverter. Result is higher output for stage use. Output measures 13.125 volts into 4 ohms... (math) about 43 watts.

Mojotone covered my cabinet in black tolex, at my request. I ditched their excellent hardware and substituted all stainless steel fasteners, and implemented T-nuts on the baffle. Beauty "finishing washers" added as well.

I think I've got an amp to last me a lifetime.
