This choice would be left up to the builder though I would always suggest that if you have no previous experience, build the kit first to get familiar with everything and then attempt the mods. If you are experienced and comfortable with the schematic, feel free to work the mods in during the build.

Is it better to drill the additional holes for these additions before you start adding the components to the enclosure, or can you drill the holes after the amp is built?

If you are planning to do the mods for certain I'd see no reason why you couldn't pre-drill the enclosure.

Running two 30 watt speakers will give you a total of 60 watts. Typically you want your speaker wattage to be greater than the amps wattage. Two Vintage 30's will work but you will want to be careful if you run this amp maxed out as you increase the potential to blow your speakers.
November 26th, 2018
More specifically, the ideal is that the speaker power rating is twice the wattage to accommodate a square wave deep into distortion, so you'd want at least 120 Watt speaker(s). Soooo, 4 30W speakers or some other combination.
December 13th, 2018
It all depends on the long term power rating of the speaker. Anyone can answer whatever they want here, but I have seen speakers rated at 30 watts with a long term power output of 80 watts, with peak power output of over 200 watts. So again, it depends what the manufacturer says about your specific speaker. If they dont say long term power output, call them and ask.

The MOD101 can be used as a bass amp though depending on your preference some modification may need to be done to the tone stack. Also, you must take into account that it will be pushing 60 watts so it will still be in the lower wattage bass amp category.

This does not come with an effects loop but these kits are designed with modding in mind! Do a search for B-707. This book has a section on modding an amp for an effects loop.

I bought this amp kit for my second build as my first was a success and so was this one and I might add a very loud and great amp will be buying foot peddles next. I will for sure buy from Amplified Parts again.

I built this amp also. It was okay in stock form, nothing to call home about. I've since changed a lot of the circuit, especially the preamp. The amp really sings now. As for the schematic, if you email modamp (, they will send you one. They were very quick to send me the diagram, and also answered some questions I had during the build.

This kit was my first amp build. I had fun and learned a lot while putting it together. Now I have a great time gigging with it! (I carry it to gigs in a duffle bag which is much better than lugging it around by the handles).I bought a black painted steel cage and white chicken head knobs to match my Marshall 4x12 cab better. I also use a Hot Plate to get some rich creamy overdrive distortion from this amp at full blast.After demonstrating clean and overdrive sounds at sound check the other night, the sound man walked up to me on stage and said, "Hey, man... your setup is solid!" Thanks, dude... I know.
