I have an Engelhardt 3/4 bass. i aint had it long but ive been a musician for a long time and swapping to this was no problem. but here is my problem. another upright bass player selected my strings, at the time i told him to get me what he used...so i currently have Innovation Rockabilly strings. im wanting to get some "slap" out of it but so far im having no luck. i see videos online of people slapping with no effort, but i have to rip my fingers off to get these strings to do it, and they dont do it good then. i play mostly country and rockabilly...wanting to add in a little bit of that slap into it. but the strings i have now just seem "hard". these upright strings are expensive, so its not like my guitars, $4 a set and i can try as many different kinds as i want, i have to make it count. i love the sound of these Innovation Rockabilly strings, but wanting something a little more "slap" friendly. anyone got a suggestion thats not a fortune for some good strings? ive looked into the weedwackers because they are super cheap, BUT, im reading not so good reviews.. the weedwacker pro's seem to have better reviews but not alot about them. as of now, my attention so far at the moment would be the weedwacker pro if i could get good feedback, OR, Innovation Silver Slaps.... any suggestions?
