Get the tone
As this style is predominantly acoustic, the best thing you can do to improve your tone and maximise you volume and projection is to sort out your picking. Use the heaviest pick you can manage and attempt to introduce each new string with a downstroke. Most modern gypsy players play with a relaxed ‘broken’ wrist posture and pick through each string, so a note on the second string ends with the pick resting on the first rather like a classical guitar rest stroke. Use gravity and the weight of the hand here rather than brute force as this will create tension in the wrist, slow you down and produce a sound that is tight and forced, rather than fluid and smooth.
