The Boss DS-1 is pretty good for a generic distortion pedal ....I used to use one years ago ...
The DS-1 is nice if you are using a Super Strat w 2 humbuckers ...it can sound very fizzy w single coils ....
You may want to compare the Boss DS-1 to the Boss SD-1 when you go out shopping around ...
IMHO the SD-1 is much more versatile sounding pedal and it can cover many more styles of guitar playing convincingly ...
The SD-1 is a very good choice for a guitarist that plays dynamically , if you hit soft , it overdrives soft .
When you dig into the strings during a phrase while you are playing the SD-1 it will overdrive along the lines of what a tube amp will do...
I happen to still prefer the SD-1 over the Tube Screamer ..I've had both from the vintage era 80's
Just about every gig I have done in the past 30 years involved using an SD-1, my amp , my guitar , 2 guitar cables , a strap and a guitar tuner
For other choices , since you have a Roland Cube 30 you may want to look into trying out the Pro Co RAT ...
The Pro Co Rat sounds fantastic going into Roland Amps ...I used to use a Rat when I had a JC 120 ...
The Rat can do heavy distortion like the DS-1 and it can also do a very nice Overdrive just like the SD-1 can ...
On my pedal board right now I use in place of a RAT the MXR M78 1978 Custom Badass Distortion Effect Pedal
I happen to feel it is a pretty nice pedal , I've had one since it came out ....this pedal for a non boutique pedal can cover a lot of ground
They can be a little tricky to dial a tone in ...it can go from to much to not enough ....
Another low cost distortion pedal I happen to love is The Nano Muff which I have ...
that pedal is meant to be left in the signal chain for when you want to go from somewhat clean to overdrive sounds
it sounds very good . Plus it has a nice feel and sound to the distortion as you play ...meaning what you do on the neck comes out of the amp ...
The SD-1 , The Nano Muff and the M78 1978 Custom Badass Distortion are the 3 I own currently ...
If I had to play out tonight and I didn't want to bring my pedal board , I would just bring the SD-1 , my guitar, my amp , 2 guitar cables , a guitar strap and a guitar tuner
I keep repeating my self ...there is a reason
all the best,
Kenny
