MADAMP J5MK1 Ultimate Collection
**TL;DR Description**
The MADAMP J5MK1 is a 5 Watt DIY-Kit Plexi-Clone. I hope you can find something usable in my profile collection. Have fun :)
**Detailed Description**
1. WHAT IS THIS
The MADAMP J5MK1 is a 5 Watt DIY-Kit Plexi-clone. My grandpa built this with me in 2014, so I branded it "Manfred" in memory of him and the good times we spend together when building this amp.
Other than the obvious downsizing in output power this amp has a few modifications that make it a little more usable while still delivering these classic tones that we all know and love (details in the frontpanel explanation section). If you want to build this amp for yourself I provided a link in the website section below. This amp features two 12AX7 tubes in the preamp and one EL84 in the power amp. Don't let the 5 watts fool you, I played this thing live with the front of house telling me to turn down, also I put this next to a drummer on a 4x12 with him telling me to turn down because he had some trouble keeping up with the volume.
2. FRONTPANEL
"Volume" and "Gain":
These control the two preamp valves individually and behave like the high and low treble gain controls on a plexi
"Fat" switch:
Adds a low-end hump which can be useful if you play quietly at home, on louder volumes it can get a bit muddy
"Bass", "Middle" and "Treble":
Now these do a little bit more than your classic Marshall EQ, but don't expect too much unless you are doing serious changes
"Master":
Mastervolume that adds power amp saturation as you go up. This type of distortion is not tight but that might be exactly what you're after. I made two captures that are explicitly made around high power amp saturation, the others have minimal amounts - added to taste, just to keep things a bit tighter and low noise floor.
"Gain" switch:
Deactivates or activates the second preamp tube (V2). This is like an internal jumper (like patching the two channels on old plexis).
"HCF" switch:
High cut filter that removes some of the super harsh high end that's sometimes hard to deal with in classic Marshalls (witch certain guitars or speakers or rooms). Sometimes absolutely necessery, sometimes better to turn off because it gives you a nice lead boost and helps cut through a mix or band.
