Lots of Folks love these little devils. Seasick Steve and Hollowbelly ply them to name a few. Well mine sounded great for the last 4 years, but after experimenting with my homemade bass, the speaker started flapping around and making "fart" type noises-not good! I stopped playing it entirely.
Then, I thought, why not replace the speaker. Even better, Upgrade that little 5" 2 watter! So I found a Jenson MOD 6-15.
It is a 4 ohm speaker just like the stock one except this on is a bit larger and is a 15 watter. Time to move on up!
Ordered it off Amazon for under $30.

I noticed that I never gave an update on the upgrades on this amp. Let me tell you, I love this amp even more!!! Much better bass response and overall sound. The only negatives would be that it does go through batteries more quickly, but not that bad. I noticed that rechargeable batteries don’t last very long.
I tried taking the cab completely apart to trim for the speaker hole, but this sucker is glued tight. I run the risk of cracking the particle board. I enlarged the hole in the baffle with a jigsaw. Note the "bridge plate" I added to keep the saw steady and level-yup its just an inside piece from a cigar box. It worked very well.
Hey Ted, I bought a small bass amp so I don't ruin anymore guitar speakers. Did you know they make a Roland Cube Bass amp? That might be the way to go.
Here's what it looks like before the operation. I taped off an area to get an idea of where I had to do some trimming to the enclosure. I've seen others Mod these, but they took the easy way and mounted the speaker inside. As a result there is no room for the battery pack in back and requires relocation.
Looks like the MOD will just barely fit, but you'll hafta drill new screw holes, and increase the size of the cone hole in the baffle.
please let me know if this works with the micro cubes. One thing that I tried and it did not work, was to use a standard analog transistor guitar amp and put a bass speaker on it and play a bass through it. It did not play clean and overheated the amp very quickly. I talked to a professional bass player, my brother-in-law and he laughed and told me I was lucky I did not burn out the amp...saying that a guitar amp is a totally different creature then a bass amp...a bass amp pushes much longer wavelengths, some over 15' long...so the power and frequency filtering is much different then in a standard guitar amp. But Then Again... A Micro Cube is Not an ordinary guitar amp and I hope it works.! I am starting a CBG Rock-N-Blues jug band with my niece and her husband called..."The Rolynn Cubes" or "Rolling Cubes" and just use micro cubes for all the amplification. lol
Here's a comparison. The speaker above is a 2 watt 4 ohm 4.75" speaker. Below is the new Jenson MOD 15.
Will it fit?
