It's not as versatile, but especially if you have one that has dedicated knobs for the blend-modes, it may be a cheaper option than the modules mentioned above. Here I can find the After Later Audio Typhoon for 250 euros for example. This way you can easily check if granular/looping delays are something that fits your style.

Thanks so much for the idea! I'm definitely trying to save some money and this seems like a great option to test stuff out.
