Hi there!
What is the intended use? Bedroom or in a band? What pedal is giving you trouble? What is your objective with the pedal?
I ask because most people buy amps that are way too loud and, literally, cannot dial them in because 7-o'clock on the dial is silent and 7-oh-five is too loud! I am willing to bet that the Champion 100 would be too loud. Even the Champion 40 might be too loud.
If you're into math and overanalyzing, this is a fantastic video to explain how amps and speakers lead to loudness.

In my opinion, bedroom levels should be under 90dB and preferably under 85dB. That is the higest level OSHA (U.S. government organization that analyzes industrial safety) recommends for 8+hours of exposure without hearing damage.
Note that virually *all* guitar amps are above 90dB unless you use an attenuator or get a dedicated practice amp. So if you are a bedroom player, I would look at those tiny Yamaha lunchboxes. *Or* diagnose why your pedal is not working. Or get another pedal.
For Loudness Reference,
OSHA guidelines for avoiding hearing damage = 85-90dB
OSHA estimate for rock concert with modern PA system = 110-115dB (with the PA system doing the work of making it loud)
A Fender Princeton Reverb (that internet pundits say is giggable 80% of the time and too soft 20% of the time) puts out a theoretical 105 dB. 15 watts through a 10-inch speaker.
A Fender Deluxe Reverb (that internet pundits say is too loud 80% of the time and giggable 20% of the time) puts out a theoretical 112dB
A Vox AC30 with Alinco Blues (that pretty much everyone says is too loud 99% of the time) puts out a theoretical 118dB
If you are looking to play in a band or go to jam sessions, 15-20 watts into a 10-inch speaker should work. 10-15 watts into a 12-inch speaker should also work. You are looking for 105-110 decibels.
Likely candidates here are
* Your current amp (solid state. has a master volume)
* Fender Super Champ (tube. has a master volume)
* Roland Blues Cube (solid state, has a master volume, has a solo boost)
Back to the pedal What is your intended use? A wise person (who I ignored and now have a smaller bank account for it) told me "Get your tone from your amp not pedals. Use pedals for special situations."
That is the reason I am asking about the pedal. A $150 amp and $300 in pedals and you could simply buy a nicer amp.
In my opinion, here are the pedals you need in the order you need them...
1. Tuner pedal
2. Noise gate
3. Some sort of method to get a louder, slightly dirtier signal for single-note playing. Some amps (like the Roland Blues Cube) have this built in.
