MOD 102+ Guitar Amp Kit

Product Files

The MOD102+ expands on the same all analog vacuum tube classic American circuit design combined with a British style Class A output section as the Original MOD102 with some much added special “+” features. These special features include a three position progressive toggle switch for off-standby-power and additional push-pull functionality for each control - pull out the bass control knob for “mid boost”, pull out the treble control knob for “bright”, pull out the volume control knob for “turbo”. These new features and a JJ ECC803-S (a long plate 12AX7 known for its complex mid range tones) allow for a wider variety of tones and extra control for the user.

Can I use this amp with high wattage speakers or do I need to get something with a lower power rating?

You can go up in speaker wattage but you do not want to go down too low. An 80-90W speaker will work as long as the ohms match. Since this is an 8 watt amp, it is not going to, "push" your speaker to its full potential and break it up. Some people like speaker breakup and some people don't, but using a high wattage speaker will not cause any damage.

You would have to add the necessary circuitry and drill holes for the hardware and tube or tubes but it's certainly possible!

Can use a 16ohm Speaker? And if so, what are the trade-offs?

You can a 16 ohm speaker. The amp will break up sooner at lower volumes which can sound great. You will not get the full output of the amp though. To get the full range of volume you'd want to use an 8 ohm.

What would happen if you swapped out the preamp tube for one with a little less gain?

I would expect some volume reduction with a little more clean as you turn up the volume pot. This is still a single ended amp so clean is relative of course.
