what pedal for a beginner

Hi everyone,

I have a bullet Harmonica Microphone (D112/C Superlux) which plays through a yamaha MG06X mixer and I listen with headphones (I have no amp yet).

I want to add some effect to my harmonica and am thinking of buying the Zoom Multi-Stomp MS-50G which is less expensive than a delay pedal, a reverb pedal and an amp.

I am guessing that with this multi-effect and time I will learn more about effects and know better what I will want to buy.

Is this a good choice ?

What would you propose ?

Thanks,

Bod
